3 - 3 squared = 6 * * * * * NO! 3 - 3 squared = 3 - 9 = -6
32*5 - 6/2 = 9*5 - 6/2 = 45 - 3 = 42
It simplifies to 5a+4 !
The answer depends on what the question is!
4
(x - 2)(2x + 3)
3
x >2 x2 - x - 6/(x2 - 4) (x + 2)(x - 3)/(x + 2)(x - 2) cross out x + 2 (x - 3)/(x - 2) this is the most simplified this can be
4
y² - y - 6 = (y + 2)(y - 3)
