Question

Find the sum of the polynomials: (x2 + 4x + 5) + (3x – 3)

Answer 1

+2x6 + 4x5 + x4 + 11x3 + 2x2 + 4x + 4

Answer 2

Answer:

x^2+7x+2

Step-by-step explanation:

hi! you can only combine terms with the same power (exponent value).

if we stack this like a regular addition problem, it will be easier.

x^2  +  4x  +  5

           3x  -   3

-----------------------

4x+3x is 7x, and 5+ (-3) is 2. we keep the x^2 the same.

therefore, the answer is x^2+7x+2

hope this helps!
