Question
Factor each expression, if possible. Factor out any GCF first (including $-1$ if the leading coefficient is negative).$$-3 a^{2}+a b+2 b^{2}$$
Step 1
In this case, the only common factor is $-1$. So, we factor out $-1$ from the expression: $$ -3 a^{2}+a b+2 b^{2} = -1(3 a^{2}-a b-2 b^{2}) $$ Show more…
