3x2 + 27x = 30

∴ x2 + 9x - 10 = 0

∴ (x + 10)(x - 1) = 0

∴ x ∈ {-10, 1}

That doesn't factor neatly. Applying the quadratic formula, we find two imaginary solutions: (-3 plus or minus 2i times the square root of 3) divided by 3.x = -1 + 1.1547005383792515ix = -1 - 1.1547005383792515iwhere i is the square root of negative one.

21x2 + 27x - 30 = 3*(7x2 + 9x - 10) = 3*(7x2 - 5x + 14x - 10) =3*[x*(7x - 5) + 2*(7x - 5)] = 3*(7x - 5)*(x + 2)
