Question

find the coefficent of x^2 in(2-3x^2)(x^2-5)​

Answer 1

Answer:

$2( {x}^{2} - 5) - 3 {x}^{2} ( {x}^{2} - 5) \\ 2 {x}^{2} - 10 - 3 {x}^{4} + 15 {x}^{2} \\ 17 {x}^{2} - 10 - 3 {x}^{4}$

hence coefficient of x^2 is 17

Answer 2

Answer:

The coefficient of x^2 is 17.

Step-by-step explanation:

  =     (2-3x^2) (x^2-5)​

  =     2(x^2-5) -3x^2(x^2-5)​

  =     2x^2-10-3x^4+15x^2

  =     17x^2-10-3x^4

          coefficient of x^2 is 17
