When you do (7x)2, you square both numbers.So 7 squared=49 and x squared=x2Your answer should be 49x2Let's try another example: 2(3xy)3Now we cube each number in the parentheses. 2(33x3y3)=2(27x3y3)Finally you multiply the 2 and the 27. 54x3y3
(x - 5)(x + 12)
(x + 2)(x - 9)
2x2 + 7x - 15 = (2x - 3)(x + 5)

X squared + 7X + 12?
7x-x2 = x(7-x)
if its x(squared) its 7x(cubed) if its 2xX its 14x(squared)
Assuming that it is only the x that is being squared. (-21x^2)/39 = (-7x^2)/13
(7x - 10)(x + 1)

x(x - 7)
7x + 8
(x2 + 7x - 18) = (x + 9)(x - 2)
If you mean: x squared -7x +12 then it is (x-3)(x-4) when factored
x(x-7)
It is: x(x+7) when factorized
