Answer:
10X^2-42X+8=0
Step-by-step 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:
10 x² - 42 x + 8.
Step-by-step 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.
