x^{2} - 9 x + 7 = 0

x = \frac{53 + 9}{2}, x = \frac{- 53 + 9}{2}

Decimal Notation

x = 8.14005 \dots, x = 0.85994 \dots

Solution steps

x^{2} - 9 x + 7 = 0

Move

7

to the right side

x^{2} - 9 x = - 7

Rewrite in the form

(x + a)^{2} = b

(x - \frac{9}{2})^{2} = \frac{53}{4}

For

the solutions are

f (x) = a, - a

Solve

x - \frac{9}{2} = \frac{53}{4} : x = \frac{53 + 9}{2}

Solve

x - \frac{9}{2} = - \frac{53}{4} : x = \frac{- 53 + 9}{2}

The solutions to the quadratic equation are:

x = \frac{53 + 9}{2}, x = \frac{- 53 + 9}{2}

7 = x (x - 4)

15 x^{2} - 4 x - 126 = - 30

\frac{k ^{2}}{1.2 - 7} = 23

x^{2} - 4 + 3 = 0

6 x^{2} - 2 x = 20
