What is the sum of x^2 - 3x + 7 and 3x^2 + 5x - 9

Dmitrij [34]

Hey there!

The answer to your question is $4x^2+2x-2$

Given:

$x^2-3x+7$ $and$ $3x^2 +5x-9$

First, we can start by adding like terms. The following are like terms:

$x^2$ $and$ $3x^2$

$-3x$ $and$ $5x$

$7$ $and$ $-9$

Now, we can add these pairs together, giving us:

$4x^2$

$2x$

$-2$

Now, add all this together, and we get our answer as:

$4x^2 + 2x - 2$

Have a terrificly amazing day!
