[gjbarnes1]

Hi I am having trouble factoring the following polynomial...Please help

27x^2 + 75

This is my answer : 3(9x^2 + 25)...Can it be factored out anymore??? this is where I get confuse

2nd Question:

10a^4 b^2-15ab-25a^2 b^4

My answer 5a^2 b^2(2a^2-3ab-5b^2)....Can be be factored out anymore? If so please explain how do I factor...Thank you for your assistance in advance.

Hi Gloria,

You first one looks good. However, the second one needs a little help.

\(\displaystyle 10a^4b^2-15ab-25a^2b^4\) has \(\displaystyle 5ab\) as its common factor, not \(\displaystyle 5a^2b^2\)
