Determine the slope of the line through points (0, -4) and (5, -9)
X^2+6x-8 / x-2
4x-2=6x+4
-91=9+8
X^2-6x=-8
x^2-6x+8=0
x^2-4x-2x+8=0
x(x-4)-2(x-4)=0
(x-2)(x-4)=0
x=2,4
x^2-6x+8=0
x^2-4x-2x+8=0
x(x-4)-2(x-4)=0
(x-2)(x-4)=0
x=2,4
Add 8 to both sides, then factor
x2 - 6x + 8 = 0
(x-4)(x-2) = 0
This will be true if either of the factors is zero.
X-4 = 0
x = 4
x-2 = 0
x = 2
The solutions to the equation are x = 2 or 4.
x2 - 6x + 8 = 0
(x-4)(x-2) = 0
This will be true if either of the factors is zero.
X-4 = 0
x = 4
x-2 = 0
x = 2
The solutions to the equation are x = 2 or 4.
