Question

How do I solve -3p^2+66p=0

Answer 1

Have you been talking about factoring in class? We can solve it that way.

Answer 2

I have learned factoring but I do not know what to do for this problem

Answer 3

That's all right. Begin by factoring out what is common to all terms. Here is an example...

9x^2 - 81x = 0

In this problem, all terms have an x in them and all terms are divisible by 9. The common term is "9x," so factor that out.

9x(x - 9) = 0

If you want to check, just distribute the 9x in, and we get our original.

Now set each term equal to 0.

9x = 0, x - 9 = 0
x = 0, x = 9
Those are our answers.

What do you come up with for your problem?

Answer 4

I got 3p(-p^2+22)

Now what

Answer 5

That's close, but you forgot to factor the p out of -3p^2. You should have

3p(-p+22) = 0

Then, set each term equal to 0.
