Which expression is equal to the polynomial below?
2x4 5x3 – 8x – 20
x3(2x 5) 4(2x – 5)
x3(2x 5) – 4(2x 5)
x3(2x – 5) – 4(2x – 5)
x3(2x 5) 4(2x 5)

Option (b) is correct.

 is equal to the given polynomial  

Step-by-step explanation:

Given polynomial

We have to choose form the given option that is equal to the given polynomial  

Consider the given polynomial    

We will factorize the  given polynomial by  grouping like terms.

Taking common from first two term and -4 common from last two term , we have,

Again taking (2x +5) common from both terms, we get

Thus, Option (b) is correct.
