Resolve(17x²+14x + 9) – (-13x² +6x - 12)

30xsquared+20x+21

I'll try to be helpful and show the work. This is the method I learned last quarter.

(17x"sq"+14x+9)

+ (13x"sq"+6x+12)

=

(30X"sq"+20x+21)

I used the vertical method but the step are the same either way.

Step 1: Remove parentheses

Step 2: Combine like terms

Step 3: Simplify

I hoped I helped. Polynomials can be rather simple if you know the short cuts.

oh, and if you use the vertical method, don't forget to change the signs. When subtracting a negative it becomes adding a positive.

could you help me with this problem? y=3(x+5)(x-2)...the answer is supposed to be y=3xsquared+ 9x-30...how did they get the -30
