Question

Can u plu Ans this i Will mark u as thé branliest​

Answer 1

Answer:

( 2x- 5)² = 4x²- 25+ 20x

therefore the coefficient of x square is 4

Answer 2

(2x-5) (2x^2-3x+1)

= 2x (2x^2-3x+1) - 5(2x^2-3x+1)

= 4x^3 - 6x^2 + 2x - 10x^2 + 15x - 5

= 4x^3 - 16x^2 + 17x - 5

Now, degree is 3 and

no. of terms are 4

coefficient of x^2 is -16 .

HOPE IT HELPS YOU,
