9(2x - 1)(2x + 1)
(x - 1)(2x - 9)
y squared minus 9 (y*y)- 9 cannot be solved because there is no given value for 9.
9 minus 8
8M - 4M - 6 - 3 + 5M = 82 - 1 9M - 9 = 64 - 1 9M - 9 = 63 9M - 9 +9 = 63 + 9 9M = 72 9M/9 = 72/9 M = 8
No, unless "a" happens to be equal to 0, or to 1.
sin squared
I believe it is prime as you have written it. change the end to + 81 and it factors as (2x - 1)(x-9)(x+9)
It is: 9-4 = 5
3 - 3 squared = 6 * * * * * NO! 3 - 3 squared = 3 - 9 = -6
-1² = 1
x^2 +8x -9 is equivalent to (x+9)(x-1) when factored
