Question

what is the answer too (5a-2a^2)-(-9a-4)

Answer 1

If it's just you needing to factorize, just expand everything out first, then collect like terms, look for common factors and take them out. So,

Answer 2

\[5a-2a^2-(-9a-4)=5a-2a^2+9a+4=-2a^2+14a+4\]

Answer 3

There is a common factor of 2, so\[2(-a^2+7a+2)\]would be your answer.
