There is a formula for "the difference of squares."
(x + 7)(x - 7) = 0
x = 7, -7
676
The number 7 raised to the 2nd power (or squared) equals 49.
1.5 to the 2nd power equals 2.25
15 to the 2nd power or 15 squared equals 15 * 15 which equals 225.
4 to the 2nd power that is the right answer promise
676
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.
-4
1.5 to the 2nd power equals 2.25
2x2-x-15 = 0 When factorised: (2x+5)(x-3) = 0
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.
