Question

what is the value of x (10x-20) (6x+8)

Answer 1

$x(10x - 20)(6x + 8) \\ x(10x(6x + 8) - 20(6x + 8)) \\ x(60x {}^{2} + 80x - 120x - 160) \\ 60x {}^{3} + 80x {}^{2} - 120x {}^{2} - 160x \\ 60x {}^{3} - 40x {}^{2} - 160x$

Answer 2

Answer:

The value of x=7  

Step-by-step explanation:

What is the value of x (10x-20) (6x+8)

We simplify the equation to the form, which is simple to understand  

(10x-20)=(6x+8)

Remove the bracts’  

10x-20=6x+8

We move all terms x to the left and all other terms to the right.  

+10x-6x=+8+20

We simplify left and right side of the equation.  

+4x=+28

We divide both sides of the equation by 4 to get x.  

x=7
