64x2-80x+25 = (8x-5)(8x-5) when factored
-2 times -2 = plus 4 since minus times minus is plus
10^2 minus 4 times 8 divided by 8 plus 9 is equal to 105.
(b-c)(a+b)-ac
x = +11 or -11
2(a + 7)(a - 6)
No.
6a to the second power minus 8ab + 2a
(-7x + 3)(-7x +3)
(2x - 1)(x + 4)
It is a polynomial expression in x. What about it?
-2 times -2 = plus 4 since minus times minus is plus
it is prime. it cannot factor out.
31
(c + d)(c + d)
simplified it would equal: 24x to the third power - x to the second power - x to the sixth power - 34

4x2-20+25 = (2x-5)(2x-5) when factored with the help of the quadratic equation formula.
