Solve equation using the quadratic formula
4m^2 - 8m + 1 = 0
Answer by nerdybill(7384) (Show Source): You can put this solution on YOUR website!
4m^2 - 8m + 1 = 0
.
To solve,
always try factoring first
failing that, use the quadratic equation.
.
In this case, we must use the quadratic equation.
Doing so will yield:
m = {1.866, 0.134}
.

Quadratic equation (in our case ) has the following solutons:

For these solutions to exist, the discriminant should not be a negative number.

First, we need to compute the discriminant : .

Discriminant d=48 is greater than zero. That means that there are two solutions: .

Quadratic expression can be factored:

Again, the answer is: 1.86602540378444, 0.133974596215561. Here's your graph:
