X squared equals x times x.
The factors of x2 are x and x.
The factors of x2 are x and x x times x plus 1 = x2 + x
x2 - 13 + 30 = x2 + 17, which has no real factors.
The factors of x2 - x - 20 are (x - 5) and (x + 4) because when you multiply them together, they come out to x2 - x - 20.

Factors of X2 - 16 are (X + 4) and (X - 4).
-2
x2 + 18x - 50 does not have rational factors.
If: x2 = 81 Then: x = 9 or x = -9
x2 + 3x + 2 factors into (x + 1) (x + 2)
If the expression is, x2 + 2x - 15 this has factors of (x + 5)(x - 3). If the expression is, x2 - 2x - 15 then the factors are (x - 5)(x + 3)
x2 - 5x + 6 = (x - 2)(x - 3)
