Question

Add (2x+3) and (3x2 + 8x -3) = _________.

Answer 1

Answer:

The sum of $2x+3$ and $3x^2+8x-3$ is $3x^2+10x$ .

Step-by-step explanation:

Given the expressions,

$P(x)= 2x+3$

and

$Q(x)=3x^2+8x-3$

We need to add $P(x)$ and $Q(x)$ . We should add term by term. The constant terms should be added together, the terms containing $x$ should be added  together and the terms of $x^2$ should add together.

Thus we have,

$P(x)+Q(x)=2x+3+3x^2+8x-3=3x^2+2x+8x+3-3=3x^2+10x$

So the sum is $3x^2+10x$ .
