Add $\left( 3 s ^ { 2 } + 7 s + 2 \right)$ to $\left( 5 s ^ { 2 } + 9 s - 1 \right)$
A) $8 s ^ { 4 } + 16 s + 1$
B) $8 s ^ { 2 } + 16 s + 1$
C) $8 s ^ { 2 } + 16 s + 3$
D) $- 2 s ^ { 2 } - 2 s + 1$

Quizplus · Accepted Answer

To add the two polynomials, you combine like terms: $3s^2 + 5s^2 = 8s^2$, $7s + 9s = 16s$, and $2 - 1 = 1$, resulting in $8s^2 + 16s + 1$.

Add (3s2+7s+2)\left( 3 s ^ { 2 } + 7 s + 2 \right)(3s2+7s+2)

Add $\left( 3 s ^ { 2 } + 7 s + 2 \right)$
