Question

What is the sum of the polynomials?

(6x+7+x²)+(2x²-3)
O-x²+6x+4
O3x²+6x+4
O9x + 4
O gx² +4

Answer 1

3x² + 6x + 4

Explanation:

6x + 7 + x² + 2x² - 3

→ Collect like terms

x² + 2x² + 6x + 7 - 3

→ Simplify

3x² + 6x + 4

Answer 2

3x^2+6x+4

Explanation:

We can find the sum of the polynomials by combining like terms.

(6x+7+x²)+(2x²-3)

x^2+2x^2+6x+7-3

3x^2+6x+4
