Question

Find the co-efficient of x^2 in the following polynomials:
(2x-5) (2x^2-3x+1)

Answer 1

Answer:

Step-by-step explanation:

(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 .
