How would you solve this equation?
I cant find anything for this. Would this answer be a fraction? 12x^2-7x+1.

12x² - 7x = - 1
x² - 7/24x = - 1/12 + (- 7/24)²
x² - 7/24x = - 48/576 + 49/576
(x - 7/24)² = 1/576
x - 7/24 = ± 1/24
x = 1/24 + 7/24, x = 8/24, x = 1/3
x = - 1/24 + 7/24, x = 6/24, x = 1/4
Answer: x = 1/3, 1/4

We can't "solve" - there's no "=" sign in the problem;
but we can "factor": 12x² - 7x + 1 = (3x-1) (4x-1)

i would factor it. such as 12x^2-3x-4x+1
then i would combine the terms so as to get a common factor
it would look like this: 12x^2-3x + (-4x+1)
then i would take out a -3x in the first equation. that leaves me with -3x(-4x+1) + 1(-4x+1)
then you are left with-3x+1 and -4x+1.
then solve for x

x2 - 7/12x + 1/12 = 0
x2 - 7/12x + (-7/24)2 = -1/12 + (-7/24)
(x -7/24)^2 = -2/24 + -7/24
-9/24 = (x-7/24)^2 remove the square by square root.
x-7/24 = square root of (-9/24)
x = square root of (-9/24) +7/24
goodluck. goodnight.
