Question

the co-efficient of x² in (3x²-5) (4+4x²) is​

Answer 1

Answer:

solution

f(x) = x^3/3 +2x^2 -3x -2

differentiating with respect to X

f'(x) = x^2+4x -2

Answer 2

Answer:

coefficient of x^2= -8

Step-by-step explanation:

(3x^2-5)(4+4x^2)

12x^2+12x^3-20-20x^2

12x^2-20x^2

-8x^2

coefficient of x^2= -8
