Question
Add the given polynomials.$12 a^{2} b^{2}-9 a b$ and $5 a^{2} b^{2}+4 a b$
Step 1
In the first polynomial, $12 a^{2} b^{2}$ and $-9 a b$ are the terms. In the second polynomial, $5 a^{2} b^{2}$ and $4 a b$ are the terms. The like terms are $12 a^{2} b^{2}$ and $5 a^{2} b^{2}$, and $-9 a b$ and $4 a b$. Show more…
