Answer:
[tex]2a^2+9ab+(-7b^2)[/tex]
Step-by-step explanation:
To subtract the following polynomials:
[tex](5a^2+4ab-3b^2)-(-5ab + 4b^2 + 3a^2)[/tex]
Remove the open parenthesis we have;
[tex]5a^2+4ab-3b^2+5ab - 4b^2- 3a^2[/tex]
Combine like terms;
[tex]2a^2+9ab-7b^2[/tex]
⇒[tex]2a^2+9ab+(-7b^2)[/tex]
Therefore, after subtracting [tex](5a^2+4ab-3b^2)-(-5ab + 4b^2 + 3a^2)[/tex] we get the result,[tex]2a^2+9ab+(-7b^2)[/tex]
