Question

(3x^2+2x+3)+(x^2+x+1)

Answer 1

= 4x² + 3x + 4

Explanation:

(3x²+2x+3)+(x²+x+1)

= 3x²+x² + 2x+x + 3+1

= 4x² + 3x + 4

Answer 2

4x² + 3x + 4

Explanation:

The expression (3x^2 + 2x + 3) + (x^2 + x + 1) can be simplified by combining the like terms:

3x^2 + 2x + 3 + x^2 + x + 1 = 4x^2 + 3x + 4

So the simplified expression is 4x^2 + 3x + 4.
