Find the exact solutions and simplify as much as possible: 5x^2+1=8x.

Question

I used the quadratic formula to solve but was unsure if I am suppose to use it.

I then set the equation to zero.

Answer 1

First, express the equation in standard form, then use the quadratic formula.

5x² + 1 = 8x

5x² - 8x + 1 = 0

a = 5

b = -8

c = 1

Now you are ready to plug numbers into the quadratic formula.
