x2 + 18x - 50 does not have rational factors.
x2+2x-63 = (x-7)(x+9) when factored
That doesn't factor neatly. Applying the quadratic formula, we find two imaginary solutions: -3 plus or minus i, where i is the square root of negative 1.
(3x + 5)(x2 - 2)
x2 - x + 30 does not have any factors. If on the other hand you wanted to factor out: x2 - x - 30 Then it can be done as follows: = x2 - 6x + 5x - 30 = x(x - 6) + 5(x - 6) = (x + 5)(x - 6)
The factors of x2 are x and x x times x plus 1 = x2 + x
x2 + 3x + 2 factors into (x + 1) (x + 2)

(X + 5)(X + 1) FOIL this. X2 + 1X + 5X + 5 Gather terms. X2 + 6X + 5 ----------------------------those were the factors
x2 - 13 + 30 = x2 + 17, which has no real factors.
x2 + 13x + 12 = (x + 1)(x + 12)
x2 + 18x - 50 does not have rational factors.
(x2 + 4 - 2sqrt(3)) (x2 + 4 + 2sqrt(3))
x2 - 5x + 6 = (x - 2)(x - 3)
x2 + 8x - 20 = (x - 2)(x + 10).
x3 - x2 + x - 2 has no rational factors.
x2+5x-24 = (x-3)(x+8)
