x2-2x-15 = (x+3)(x-5) when factored
x2+2x-15 = (x+5)(x-3) when factored
4X + 2x = 1. Where x = 0.166666666666666666666666666666666666666 recurring.
X2 + 2X - 14 = 6X2 + 2X - 8 = 0what two products of - 8 = 2 ?(X +4)(X - 2)=========X = - 4X = 2
It is a quadratic expression and is (x-3)(x+5) when factored
x2 + 2x - 15 = (x - 3)(x + 5)
x2-2x-15 = (x+3)(x-5) when factored
x2 + 2x - 15 = (x + 5)(x - 3)
x2 + 2x - 15 = 0(x + 5) (x - 3) = 0x = -5x = +3
x2 + 2x -6 = 0 x2 + 2x + 1 = 7 (x + 1)2 = 7 x = -1 ± √7
x2+2x-15 = (x+5)(x-3) when factored
2x = x2 + 4x - 3 x2 + 2x - 3 = 0 (x - 1)(x - 2) = 0
The vertex is at (-1,0).
x2+2x-15
x2 + 2x - 13 = 2 x2 + 2x - 15 = 0 (x + 5)(x - 3) = 0 x + 5 = 0 and x - 3 = 0 so x = -5 and x = 3
(x2 + 2x + 15)/(x - 3) = x + 5 + 30/(x - 3) where x ≠3
