Q. Find the sum of

-3 x^{2}-4 x-8

and

2 x^{2}+7 x+10

.

\newline

Answer:

Write Polynomials: Write down the polynomials to be added. $\newline$ $-3x^{2}-4x-8$ and $2x^{2}+7x+10$ . $\newline$ We need to add these two polynomials together.
Combine Like Terms: Add the polynomials by combining like terms. $\newline$ $(-3x^{2} + 2x^{2}) + (-4x + 7x) + (-8 + 10)$
Perform Addition: Perform the addition of like terms. $\newline$ $(-3x^{2} + 2x^{2}) = -x^{2}$ $\newline$ $(-4x + 7x) = 3x$ $\newline$ $(-8 + 10) = 2$
Combine Results: Combine the results to get the final sum of the polynomials. $-x^{2} + 3x + 2$
