-22 - 12 = -8
The answer is 4 squared minus 2 squared as 4 squared is 16 minus 2 squared, which is 4, gives you 12 as an answer.
4 squared minus 2 squared equals 12
(-4)2 - 4 = 12
It is x^2 -x -12 is (x+3)(x-4) when factored
Factored, that's (x - 6)(5x + 2) x = 6, -2/5
3(x - 2)(x + 2)
(-4)^2 - ( - 2)^2 = Factor ((-4) + (-2))((-4) - (-2)) = (-4 -2)(-4 + 2) = (-6)(-2) = (+12) Or more simply 16 - 4 = (+12)
x2-10x-24 = (x+2)(x-12) when factored
answer is p/5. problem: {[(p^2)-3p]/[(p^2)-6p+9]}/{20/(4p-12)}
There is nothing to "do".
-32 - 2 - 5 = 2
It is x^2 -13x +12 = (x-1)(x-12) when factored
