Question

10x²+6xy+y²,9x²-y²,Subtract the given terms.

Answer 1

Hello!

$\sf 10x^{2} + 6xy + y^{2} - (9x^{2} - y^{2})$

⇒ $\sf 10x^{2} + 6xy + y^{2} - 9x^{2} + y^{2}$

⇒ $\sf 10x^{2} - 9x^{2} + y^{2} + y^{2} + 6xy$

⇒ $\boxed{\sf x^{2} + 2y^{2} + 6xy}$

Cheers!

Answer 2

$10x {}^{2} + 6xy + y {}^{2} - (9x {}^{2} - y {}^{2} ) \\ = 10x {}^{2} + 6xy + y {}^{2} - 9x {}^{2} + y {}^{2} \\ = x {}^{2} + 6xy + 2y {}^{2}$
hope this helps.....if correct.......
