14x2-7x2-16 7x2-16 (this can't be simplified any more)
It is undefined. Division by zero is not defined: it is not an operation that has any meaning. Consequently, an expression containing "divided by zero" is not valid.
x + 1
Actually, x2 - 12 cannot be simplified.
The answer is: X1 = 2 X2 = -7
None of the graphs that I can see!
2b - 1
x - 3
7x + 8
4x + 20
x - 5
By factoring I get x-3 divided by x+3
t2+ t - 42 it can't be simplified anymore
It is 1.
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
b2 + ab - 2 - 2b2 + 2ab = -b2 + ab - 2 which cannot be simplified further.
-1ab^2 + 5b + 8 Step-by-step explanation: 3a^2+9ab+5-4a^2-4ab+3 3a^2-4ab^2=-1ab^2 9ab-4ab=5ab 5+3=8 -1ab^2+5ab+8
It simplifies to 5a+4 !
x2 - 2x = x(x-2) and that cannot be simplified further.
