Question

subtract:- (ii) x2 - y2 from 3x2 + 2y2 + 2​

Answer 1

Answer:

2x^2+3y^2+2

Step-by-step explanation:

(3x^2+2y^2+2)-(x^2-y^2)

=3x^2+2y^2+2-x^2+y^2

=2x^2+3y^2+2

Answer 2

Answer:

$2x^{2} + 3y^{2} + 2$same signs are treated as plus sign and different signs are treated as minus sign.

Thus, following this rule, we have the solution

$2x^{2} + 3y^{2} + 2$
