Question

Write the coefficient x square of in (2x - 5)(2x² – 5x – 4)​

Answer 1

Step-by-step explanation:

we will get x^2 in the given polynomial when 2x is multiplied by (-5x) and when (-5) is multiplied by 2x^2.

so, now we add both of them and get

2x(-5x) +(-5) (2x^2)

=(-10x^2-10x^2) =-20x^2

So,the coefficient x square of in (2x - 5)(2x² – 5x – 4) is 20.
