Question

Find the sum(x2 + 2x + 3) + (3x2 + x + 1)

Answer 1

Combine like terms
x^2 + 2x + 3 + 3x^2 + x + 1
4x^2 + 3x + 4

Answer 2

Sum of (x²+ 2x + 3) and (3x² + x + 1) is:

4x²+3x+4

Explanation:

Find the sum of:

(x²+ 2x + 3) and (3x² + x + 1)

(x²+ 2x + 3) + (3x² + x + 1)

Combining the like terms, we get

= x²(1+3)+x(2+1)+(3+1)

=4x²+3x+4

Hence, sum of (x²+ 2x + 3) and (3x² + x + 1) is:

4x²+3x+4
