Pi
Ok, it really cannot be answered without knowing to what it is equal and to which form of the equation you are referring:
(7x)^2 - 14x = 49x^2 - 14x =7(7x^2 - 2x)
or
7(x^2) - 14x = 7(x^2 - 2x)
x-7
54.3 squared
x = 5 / 6squared + 7
I'm pretty sure it's x sqaured plus seven
(x−6)(x+5)
The answer is: X1 = 2 X2 = -7
x-7
54.3 squared
x = ? 42 = x squared minus x
5x2 - 27x - 18 = (5x + 3)(x - 6)
196 meters squared
By factoring I get x-3 divided by x+3
-22 - -22
x = 5 / 6squared + 7
xsquared minus x minus 72
I'm pretty sure it's x sqaured plus seven
(x - 5)(x + 4)
