Solve x^2 +x - 6 = 0 by Factoring
Переглядів 71 тис.6 років тому
Example of how to solve a quadratic equation by factoring: x^2 x - 6 = 0 (x 3) (x - 2) = 0 x = -3 or x = 2
Polynomial Long Division: (x^3 + 3x^2 + 5x + 3) / (x + 1)

An example of polynomial long division: (x^3 3x^2 5x 3) / (x 1)
Solve 15 - 5x = -40
Переглядів 1,9 тис.6 років тому
This example shows how to solve a two step algebra equation in which the variable term is subtracted from a constant. 15 - 5x = -40 -15 -15 Subtract 15 on both sides -5 x = -55 /-5 /-5 Then, divide each side by -5 x = 11
Solve 7x - 11 = 17
Переглядів 1,4 тис.6 років тому
Example of how to solve the two-step equation 7x - 11 = 17. 7x - 11 = 17 11= 11 add 11 to each side 7x = 28 /7 /7 divide by 7 on each side x = 4
Solve a Fraction Equation: 5/9 x = 2/3
Переглядів 23 тис.7 років тому
Solve an equation involving a fraction by multiplying each side of the equation by the reciprocal of the fraction next to the x. 5/9 x = 2/3 (9/5) 5/9 x = 2/3 (9/5) x = 6/5 or x = 1 1/5
Solve Two Step Equation: 7x - 8 = 27
Переглядів 2,6 тис.7 років тому
Demonstration of how to solve a two-step algebra equation by isolating the variable with algebraic operations. 7x - 8 = 27 8 8 Add 8 to both sides 7x = 35 /7 /7 Divide both sides by 7 x = 5
Solve an Absolute Value Equation: | x - 7 | = 12
Переглядів 6 тис.7 років тому
Find both solutions to an absolute value equation by splitting it into two equations (one positive and one negative). | x - 7 | = 12 x - 7 = 12 OR x - 7 = -12 x = 19 OR x = -5
Solve Absolute Value Inequality: 6|x + 3| greater than 42
Переглядів 2,1 тис.7 років тому
Demonstration of how to solve an absolute value inequality by isolating the absolute value and splitting it into two simple inequalities. 6 | x 3 | greater than (gt) 42 | x 3 | gt 7 Divide by 6 x 3 gt 7 OR x 3 lt -7 Split absolute value into 2 inequalities x gt 4 OR x lt -10 Subtract 3 from both sides in each
Graph in slope intercept form: y = -1/3 x -2
Переглядів 23 тис.7 років тому
This example uses the linear equation y = -1/3 x - 2 to demonstrate graphing from slope intercept form. Slope Intercept form is: y = mx b m = slope b = y-intercept In the example: y = -1/3x - 2 m = slope = -1/3 b = y-intercept = -2
Simplify and Solve an Algebra Equation: 7x + 8 + 2x - 5 = 3x + 10 + 2x - 27
Переглядів 23 тис.7 років тому
This example shows how to solve a multi-term algebraic equation by first combining like terms, grouping the x's on one side and constant terms on the other, then solving for x. 7x 8 2x - 5 = 3x 10 2x - 27 9x 3 = 5x - 17 4x = -20 x = -5

Thenk you so much ❤
Very nice solution😮
Thx, it rly helped with my math homework!😊😊
Thx, it rly helped with my math homework!😊😊
Thank you
Legendary vid. Helped sooo much!!!!
How to solve
Thank you❤
Hm! Very clear in explanation, taught me slope in under a minute lmfao
TYSM brother !!
Thanks gringo
This really helped me understand it better
Does this mean we can not plot the graph? If there are no values for which x = 0, shouldn't the parabola be Above or Below (inverted) the x-axis?
Thanks bro i needed this
Really helped keep it up
Am still confused
this helped me out so much thanks
thankyou so much. this video really made this sum easy.
It’s not Dumb for not knowing, It’s Absolutely Dumb for Teaching such useless Trash.
Спасибо за помощь
I think it is not defined when x=0 (V.A.), and there is no way it will be y=0 (H.A.).
nice video

Can you translate Indonesian becaue me and friends have a homework 💀
Í don't understand about think because you say in league english, sorry my english bad:v
i love you for this video thankyou

Tq😊
Huh
Tq ur explanation make my dayyy
First you learn hindi or are you ashamed to tell in hindi
Thank you
2 x minus 4 is equal to 12 solve kijiye
isn't it -1,5 instead 2?
coochie
Thank you so much sir 🔥
How do you flip it and find the guide points😭😭😭 my teacher doesn't teach
7 years later still helpful
😡😡😡😡😠😠😡😠😠😠😠😠😡😡🤮🤮🤮🤮🤮🤮🤮🤮🤮🤮🤮🤮🤮🤮🤮🤮🤮🤮🤮🤮🤮🤮🤮😡😡😡😡😡😡😡🤮🤮🤮🤮🤮🤮🤮😡😡😡
thank u v ery helpful
You’re the best I’ve been struggling with this question for hours
Thank You
Thank you so much! My teacher never explained how to plot graphs for a function like this and wants us to use functions to draw them. I understand now, thanks to this video.
धन्यवाद
