9(2x - 1)(2x + 1)
4x2 - 9 = (2x + 3)(2x - 3)
24
(4x - 3)(2x + 3)
x^2 +8x -9 is equivalent to (x+9)(x-1) when factored
(10x-3(10x+3)
y squared minus 9 (y*y)- 9 cannot be solved because there is no given value for 9.
9 minus 8
-8.
It is: 9-4 = 5
3 - 3 squared = 6 * * * * * NO! 3 - 3 squared = 3 - 9 = -6
