2x2-x-15 = 0
When factorised:
(2x+5)(x-3) = 0
x2-2x-15 = 0
(x+3)(x-5) = 0
x = -3 or x = 5
(x + 3)(x - 5)
(x - 5)(x + 3)
(2x - 9)(2x - 9) or (2x - 9)2
4x2+29x-24 = (4x-3)(x+8) when factored

The GCF is 4.
William Power came 2nd in the 2015 Indy 500. Charlie Kimball came 3rd.
There is a formula for "the difference of squares." (x + 7)(x - 7) = 0 x = 7, -7

Using the quadratic formula, you should get two answers: 1 + sqrt(14) and 1 - sqrt(14).
A quadratic equation, if there's an equals stil to come... Otherwise it's just an expression.
That depends what the value of A is.
x = -3
Factor it. y(4y - 1)(3y - 2) = 0 y = 0, 1/4, 2/3
49 - 8 - 6 = 35

The number 7 raised to the 2nd power (or squared) equals 49.
1.5 to the 2nd power equals 2.25
Would you mind typing it out for me? I don't quite understand exactly what you are asking. For example, x to the second power minus 4x over x to the second power minus 16 would be... x^2-4x/x^2-16 Do you mind typing it out like that? Because what you wrote makes no sense at all.
