-12x^2+6x=3/4
-48x^2 + 24x = 3
-48x^2 + 24x - 3 = 0
48x^2 - 24x + 3 = 0
3(16x^2 - 8x + 1) = 0
3(4x-1)(4x+1) = 0
x = 1/4
-48x^2 + 24x = 3
-48x^2 + 24x - 3 = 0
48x^2 - 24x + 3 = 0
3(16x^2 - 8x + 1) = 0
3(4x-1)(4x+1) = 0
x = 1/4
-
- 12x^2 + 6x = 0.75
multiply through by (- 4/3)
16x^2 - 8x = - 1
16x^2 - 8x + 1 = 0
perfect square trinomial...
(4x - 1)^2 = 0
x = 1/4 or 0.25
check in the original equation...

multiply each side by -4 48x^2-24x=3 then subtract each side by 3 48x^2-24x-3=0
divide by 3 each side 16x^2-8x-1=0 use quadratic formula to solve this
divide by 3 each side 16x^2-8x-1=0 use quadratic formula to solve this
-
12x^2-6x+0.75 = 0 Use the quadratic formula
x = [6±0]/24 = 1/4
x = [6±0]/24 = 1/4

hey whats the ^ for is it squared. i could probably get this.
-
factor and you get
x=0.25
x=0.25
