Question

subract
$2y {}^{2} - 3x {}^{2} from \: 7y {}^{2} + 5x {}^{2}$
​

Answer 1

Step-by-step explanation:

=7y²+5x²-(2y²-3x²)

=7y²+5x²-2y²+3x²

=5y²+8x²

Answer 2

$2y {}^{2} - 3 {x}^{2} from \: 7 {y}^{2} + 5 {x}^{2}$

$(2 {y}^{2} - 3 {x}^{2})(7 {y}^{2} + 5 {x}^{2})$

$( - 1 {x}^{2} {y}^{2} )(12 {x}^{2} {y}^{2} )$

$- 1 {x}^{2} {y}^{2} - 12 {x}^{2} {y}^{2}$
