Find the difference (5a^2+4ab-3b^2)-(-5ab+4b^2+3a^2)

Vesna [10]

Answer:

$\boxed{\bold{2a^2+9ab-7b^2}}$

Step By Step Explanation:

Remove Parenthesis: (a) = a

$\bold{5a^2+4ab-3b^2-\left(-5ab+4b^2+3a^2\right)}$

Simplify $\bold{-\left(-5ab+4b^2+3a^2\right)}$

$\bold{5ab-4b^2-3a^2}$

Rewrite Equation:

$\bold{5a^2+4ab-3b^2+5ab-4b^2-3a^2}$

Simplify $\bold{5a^2+4ab-3b^2+5ab-4b^2-3a^2}$
