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

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!
