Question

Factor the polynomials completely, Please show a work! Problems entered in comments :)

Answer 1

1) \[5y^2-20\]
2) \[4s^2-1\]
3) \[3b^3-13b^2+10b\]

Answer 2

Only one question per thread please.
When factoring, always find the greatest common factor of each number.
1) \(5y^2-20\)
What is the GCF of \(5y^2\) and \(20\)?

Answer 3

5.

Answer 4

Just give steps to solve this type rather than this specific question please.

Answer 5

Correct. Set it up like this:
\(\large 5y^2-20\rightarrow 5(?+?)\)
find what the question marks are by dividing \(5y^2\) and \(-20\) by 5.

Answer 6

With these types of problems, always search for the GCF first.

Answer 7

Okay, so the answer is (y^2+-4)?

Answer 8

not quite. You have to leave the 5 there. so \(\large 5(y^2-4)\)

Answer 9

Okay, great. Thank you!

Answer 10
