Question

Find the sum and enter it in the box below. Enter your answer as a polynomialin descending order, and use the caret (^) for exponents. For example, youwould write 4x2 as 4x^2.x" + 2x2 + 2x2 + 6x + 3-3x5 - 3x4 + 2x3 + 6x

Answer 1

When you sum two algebraic expressions, you simplify like terms (terms with variable of the same order).

Then, for the given expression you obtain:

x^5 + 2x^3 + 2x^2 + 6x + 3

-3x^5 - 3x^4 + 2x^3 + 6x

-2x^2 - 3x^4 + 4x^3 + 2x^2 + 12x + 3

Hence, the result of the sum of the given expression is:

-2x^2 - 3x^4 + 4x^3 + 2x^2 + 12x + 3
