6x-x+15-9= 6x-x=5x 15-9=6 5x+6=0 5x=-6 x=-1.2
x2 + 6x + 8 = 0 Solve for x.X = -2 or X = -4
The discriminant b2-4ac is -23
-4
5x2 + 20x = 0 5x(x + 4) = 0 x = 0 and -4
x - 6x = 0-5x= 0x = 0/-5which equals x = 0
0. 6x + 3 = 5x + 141. 6x = 5x + 11 [subtracting 3]2. x = 11 [subtracting 5x]
It is: 3x2+6x-11 = 0
6x-x+15-9= 6x-x=5x 15-9=6 5x+6=0 5x=-6 x=-1.2
2x2 - 5x = 3 ∴ 2x2 - 5x - 3 = 0 ∴ 2x2 + x - 6x - 3 = 0 ∴ x(2x + 1) - 3(2x + 1) = 0 ∴ (x - 3)(2x + 1) = 0 ∴ x ∈ {-0.5, 3 }
y + 6x - x = 0 y + 5x = 0 -y =-y 5x = -y /-1 = /-1 -5x = y m = -5 where m=slope
3x(2x + 1)
x2 + 6x + 8 = 0 Solve for x.X = -2 or X = -4
y=6x² is already solved. the parabola will touch the x-axis at x=0.
2x2 - 6x - 25 = 0. Solutions are 5.34 and -2.34
(2x-4)(x-1) = 0
your equation is this... 2x3 + 11x = 6x 2x3 + 5x = 0 x(2x2 + 5) = 0 x = 0 and (5/2)i and -(5/2)i
