When you use -b/2a you plug in a and b. in this case it would be -18/-2 which coms out as 9. then you plug 9 into x. -9^2+18(9)-75 which comes out as -12. Your vertex is (9,-12) your Axis of semmetry would be 9.

How do you factor the common factor out of 30x^2-12x

Anika [276]

The answer would be 6x(5x-2).

Since both terms have x in them, x will be apart of your answer.

The GCF of 12 and 30 is 6.

So you can factor out 6x from both terms.

Hope this helps!
