Use the different of two squares formula to factor. Be sure to factor out any common factors.
20. 49x^3 - 36x
=x(49x^2-36)
=x[ (7x)^2 -6^2]
= x(7x+6)(7x-6)
Use the perfect square trinomiel formulas to factor. Be sure to factor out any common factors.
24. 100y^2 - 20y + 1
= (10y)^2 -(2*10y*1) +1^2
= (10y +1)^2
Use the sum and difference of cubes formulas to factor. Be sure to factor out any common factors.
40. 27x^3 - 64
=(3x)^3 -4^3
= (3x-4)(9x^2 +12x+16)
Factor if possible. Be sure to factor completely.
