You can put this solution on YOUR website! FOLLOWING POLYNOMIALS:
1. 9 - x^2
Note this is the difference of square, 9 and x^2 are perfect squares, so we can:
(3 + x)(3 - x); FOIL this to prove this to yourself
:
2.4x^2 + 81 -36
Do the math on the numbers and you have;
4x^2 + 45 is about all you can do with this
:
3. 4y^2 + 16y + 16
Note you can factor out 4 here, results
4(y^2 + 4x + 4)
This is a perfect square now
4(y + 2)(y + 2)
or
4(y + 2)^2
