The answers are x = 2.33 and x=1

3x^2 - 10x + 7 = 0
                    x3

x^2 - 10x + 21 = 0

After you find the factors, you divide them by 3, since you multiplied by 3 before.

(x - 7/3) (x - 3/3)

Simplify.

(x - 2.33) (x - 1)

Equal both to zero and solve.

(x - 2.33) = 0

(x - 1) = 0

x = 2.33
x = 1
