math help!! (simplifying polynomials)?

7q - (3q) <--- just subtracted 1q from 4q

4q <----------- subtracted 3q from 7q

I'm assuming this is correct. Not the best at math, but I hope I helped.

7q - 4q + q

3q + q

4q.

Hope this helps.

You in reality have 2 words right here, (2x^2 -a million)(x+2) and four(x+2)^2. be conscious that they each and each have (x+2) in common. so which you will element that out, interior an identical way that ac - bc = (a-b)c: [ (2x^2 - a million) - 4(x+2) ] (x+2) Now boost what's interior. [ 2x^2 - a million - 4x - 8 ] (x+2) [ 2x^2 - 4x - 9 ] (x+2) often you would be able to correctly be waiting to element a quadratic, yet for that reason of 2x^2 - 4x - 9, you won't have the ability to. So this is so a ways as you could take it. >>yet i'm rubbish at maths! :| in case you do not prefer to pass interior the process something of your existence as somebody who sucks at arithmetic, then it particularly is as much as you to alter that. undesirable arithmetic skills are not genetic.

Distribute the negative no0b. Then add everything together. 4q

7q -(4q -q)

= 7q-3q

=4q
