14x2-7x2-16 7x2-16 (this can't be simplified any more)
x2 - 2x - 14 doesn't factor neatly. Applying the quadratic formula, we find two real solutions: 1 plus or minus the square root of 15x = 4.872983346207417x = -2.872983346207417
The GCF is 9. The LCM is 3528.
(x - 7)(x2 + 7x + 49)
(3x - 8)(8x + 5)
(7x + 8)(7x - 9)
The required equation is: -7x = 63
14x squared minus 7x to the 3rd power can be factored to 7x2(2-x).
7x + 8
(x + 1)(x - 8)
7x2 -4x -5x2 +2x = 2x2 -2x
No
13X squared + 7X + 12
(x + 2)(x - 9)
x(x - 7)
14x2-7x2-16 7x2-16 (this can't be simplified any more)
x2 + 7x - 56 cannot be factorised.
