The sum of 15x^2 + 3x - 4 and 5x - 4 is..?

15x^2 + 8x - 8

Step-by-step explanation:

1) Add them together

(15x^2 + 3x - 4) + (5x - 4)

2) Combine like terms

15x^2 + 8x - 8

15x^2+8x-8

Step-by-step explanation:

when asking for the sum of 2 polynomials, the question is simply asking you to add like terms

15x^2 (nothing to add so this stays the same)

3x+5x=8x

-4+(-4)=-8

add the bolded terms to get

15x^2+8x-8

constants mean the stopped points or the points on a graph that nothing is changing, hope this

answer: no, but if it does it's a obvious pattern.
