x2 + 1x - 30 = (x + 6) (x - 5)
(x+5)(x-6)

x^2 - x + 30 doesn't have rational factors. If that was - 30, it would factor to (x - 6)(x + 5)

(x + 10)(x - 3)

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)
32
(x - 10)(x - 3)
