Question

Coefficient of xsquare in (2-3xsquare) (xsquare-5) is

Answer 1

Answer:

(2-3x²)(x²-5)

2x²-10-3x⁴+15x²

-3x⁴+17x²-10

therefore , coefficient of x² is +17

Answer 2

Answer:

$coefficient \: of \: {x}^{2} in \: (2 - 3 {x}^{2} )( {x}^{2} - 5)$

$2 {x}^{2} - 10 - 3 {x}^{4} +15{x}^{2}$

$- 3 {x}^{4} + 17 {x}^{2} - 10$

$coefficient \: of \: {x}^{2} \: is \: 17$
