2a^2 + 9ab +( -7b^2)

Answer:

\(2a^2+9ab+(-7b^2)\)

Step-by-step explanation:

To subtract the following polynomials:

\((5a^2+4ab-3b^2)-(-5ab + 4b^2 + 3a^2)\)

Remove the open parenthesis we have;

\(5a^2+4ab-3b^2+5ab - 4b^2- 3a^2\)

Combine like terms;

\(2a^2+9ab-7b^2\)

⇒\(2a^2+9ab+(-7b^2)\)

Therefore, after subtracting \((5a^2+4ab-3b^2)-(-5ab + 4b^2 + 3a^2)\) we get the result,\(2a^2+9ab+(-7b^2)\)
