How do I solve -3p^2+66p=0
5 answers
Have you been talking about factoring in class? We can solve it that way.
I have learned factoring but I do not know what to do for this problem
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.

9x(x - 9) = 0

Now set each term equal to 0.
9x = 0, x - 9 = 0
x = 0, x = 9
Those are our answers.

I got 3p(-p^2+22)
Now what
Now what
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.
3p(-p+22) = 0
Then, set each term equal to 0.
