if this is x squared -6x+6=0
then
-6=b, a=1, c=6
6+ square root of -6 squared-4(6x1)
-
6+ square root of (36-24)
-
6+ square root of 12
-
6+ square root of 4 x square root of 3
-
6 + (2x square root of 3)
-
that is all divided by 2 multiplied by a
meaning it is divided by 2.
so x= 6 + or - (2 square root 3)
divided by 2
srry steps are jmbled

Yes. You can calculate the two roots of a quadratic equation by using the quadratic formula, and because there are square roots on the quadratic formula, and if the radicand is not a perfect square, so the answer to that equation has decimal.
Why use quadratic formula?
Using the quadratic formula to solve any quadratic equation is the best way of getting around it because the quadratic formula is "the opposite of b plus or minus the square root of b squared minus 4ac all divided by 2a. This formula only works with trinomials and second degree equaitons. If the equation is a binomial, then put in a placeholer (0) and substitute them into the equation.
