81w2 - p2 = (9w + p) (9w - p)
because 81w2 - p2 is the difference of squares. To factor the difference of squares, square root both terms and write the binomial twice:
(9w ? p) (9w ? p)
Now, to replace the question marks, one binomial has to replace it with the plus sign, while the other binomial gets a minus sign:
(9w + p) (9w - p)
No.
No.
9xy(3xy - 4)
x-a is a factor of the polynomial p(x),if p(a)=0.also,if x-a is a factor of p(x), p(a)=0.
(p+9)(p+6)
p2-2p = p(p-2) when factored
P squared = P*P. When divided by P, the equation becomes (P*P/P, and the answer is "P".
3p2-2p-5 = (3p-5)(p+1) when factored
Well, darling, if we're talking math, P squared plus P squared equals 2P squared. It's as simple as that. So, next time you're trying to impress someone with your algebra skills, just remember this little gem.
-2p squared
p2 X p2 = p4or p X p X p X p = p4
p^2(p squared)
P cubed
When you divide p cubed by p squared, you are essentially dividing p to the power of 3 by p to the power of 2. This simplifies to p^(3-2), which equals p^1. Therefore, the result of p cubed divided by p squared is p.
No.
No.
p^2 x p^2 = p^4 p^2 + p^2 = 2p^2
