Q=p(r+s) solve for p

pav-90 [236]

Q = p(r+s)
--------------
(r+s) (r+s) Divide both sides by (r+s) so you can get the p bu itself this way you get q / (r+s) = p

Factor the greatest common factor from the polynomial 3x^2 + 6x -9

ryzh [129]

Answer:

$3(x+3)(x -1)$

Step-by-step explanation:

$3x^2 + 6x -9$

All the terms in this polynomial are divisible by 3. Factor 3 out of this polynomial:

$= 3(x^2 + 2x -3)$

Now, factor inside the parentheses by grouping:

$= 3(x^2 -1x+3x -3)$

We knew to split the +2x up into -1x and 3x because -1 and 3 multiply to get -3, which is the last value in the polynomial.

$= 3(x(x -1)+3(x -1))\\= 3(x+3)(x -1)$

Therefore, the final factored polynomial is $3(x+3)(x -1)$ .
