Solve the following equation

(7X3+4X2+3X+2) + (2X2+X+5) =

The way it's written it's

Simplify the following:

7 X^3 + 4 X^2 + 2 X^2 + 3 X + X + 2 + 5

Grouping like terms, 7 X^3 + 4 X^2 + 2 X^2 + 3 X + X + 2 + 5 = 7 X^3 + (4 X^2 + 2 X^2) + (3 X + X) + (2 + 5) : 7 X^3 + (4 X^2 + 2 X^2) + (3 X + X) + (2 + 5)

4 X^2 + 2 X^2 = 6 X^2:

7 X^3 + 6 X^2 + (3 X + X) + (2 + 5)

3 X + X = 4 X:

7 X^3 + 6 X^2 + 4 X + (2 + 5)

2 + 5 = 7:Answer: 7 X^3 + 6 X^2 + 4 X + 7
