Question

Multiply the binomials (5x − 1) and (2x − 8).

Answer 1

10X^2-42X+8=0

Explanation:

Multiply all whats inside the brackets, i.e 5x*2x = 10^2

and 5x*8 =40x and -1*2x =-2x

add that you get -42x

AND Finally

-1*-8 = 8

Answer 2

10 x² - 42 x + 8.

Explanation:

Given: (5x − 1) and (2x − 8).

To find : Multiply the binomials.

Solution : We have given

(5x − 1) and (2x − 8).

On distribution 5x over (2x -8) and 1 over (2x - 8)

5x (2x -8) - 1 (2x -8).

5x * 2x - 5x *8 - 2x * 1 + 8* 1.

10 x² - 40 x - 2x + 8.

10 x² - 42 x + 8.

Therefore, 10 x² - 42 x + 8.
