x2 + 3x - 10 = (x + 5)(x - 2) ⇒ x = -5 or 2

x2 + 3x - 7 = 5x + 8; thus, x2 + 3x - 7 - 5x - 8 = x2 - 2x - 15 = (x - 5)(x + 3) = 0. Therefore the solution is x = 5 or -3.

The discriminant is -11.

3x-5=3x+5 There is no solution.

x2 + 3x - 10 = (x + 5)(x - 2) ⇒ x = -5 or 2

x2 + 3x - 7 = 5x + 8; thus, x2 + 3x - 7 - 5x - 8 = x2 - 2x - 15 = (x - 5)(x + 3) = 0. Therefore the solution is x = 5 or -3.

The discriminant is -11.

x = -5 x = 2

x = 5 or x = 6

x2 + 3x - 40 = (x + 8)(x - 5)

If you factor x2 - 3x - 10, you'll get (x-5) (x+2). If your equation is x2 - 3x -10 = 0, then x = 5, and x = -2.
