Factor each of the following

1.)  = .    <--- Apply the formula  = .

2.)  =    <--- the same formula

3.)  =    <--- Apply the formula  = .

4.)  =    <--- the same formula

Do the rest yourself. Use the same formulas / the same pattern.

5.) 4x^2-20xy+25y^2

6.) 49b^2+42b+9

7.) 4x^2-2x+0.25

8.) x^2+2x/3+1/9

9.) 9x^2-4x+4/8

10.) p^2+0.4p+0.04

11.) 16x^2-24xy+9y^2

12.) 4a^2-20ab^2+25b^4

Regarding these formulas

= ,

= .
