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.
what is a slope
x2-5-4x2+3x = 0 -3x2+3x-5 = 0 or as 3x2-3x+5 = 0
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.
(x2 + 3x + 5)(x2 - 3x + 4)
3x-5=3x+5 There is no solution.
x2+3x-5 = (x+4.192582404)(x-1.192582404) factored with the help of the quadratic equation formula
