Factor completely 5ax2 − 20x3 + 2a − 8x.
(a + 4x)(5x2 + 2)
(a + 4x)(5x2 − 2)
(a − 4x)(5x2 + 2)
(a − 4x)(5x2 − 2)

C

Step-by-step explanation:

5ax²-20x³+2a-8x

=5 x²(a-4x)+2(a-4x)

=(a-4x)(5x²+2)

set each factor equal to 0

4x-3 = 0

2x-1 = 0

solve for x.

4x-3=0

4x=3

x= 3/4

solve for x. 

2x-1= 0

2x= 1

x= 1/2

your answer should be 1/2 is less than or equal to x and 3/4 is greater than or equal to x
