x2 + x2 = 2x2. Don't be thrown by squares (or other powers).
y + y = 2y. Just treat x2 like you treat y. But remember, you can only add together the same powers of x, you cannot add together x and x2 (or other powers of x).
(x-3)(x-2)
Solve using the quadratic formula
(x - 3)(x + 5)
32 + x = 259 + x = 25x = 25 - 9x = 16
It can be solved by using the quadratic equation formula.
(x-3)(x-2)
X=1
Solve using the quadratic formula
(x - 3)(x + 5)
x=9 squared
32 + x = 259 + x = 25x = 25 - 9x = 16
x2 + 6x + 8 = 0 Solve for x.X = -2 or X = -4
5.
It can be solved by using the quadratic equation formula.
x = 25 / 3squared + 5
Factor it. (x - 8)(x - 2) x = 2, 8
X = √63
