m^{2} - 9 m + 9 = 0

m = \frac{9 + 3 5}{2}, m = \frac{9 - 3 5}{2}

Decimal Notation

m = 7.85410 \dots, m = 1.14589 \dots

Solution steps

m^{2} - 9 m + 9 = 0

Solve with the quadratic formula

m_{1, 2} = \frac{- ( - 9 ) \pm ( - 9 ) ^{2} - 4 \cdot 1 \cdot 9}{2 \cdot 1}

(- 9)^{2} - 4 \cdot 1 \cdot 9 = 35

m_{1, 2} = \frac{- ( - 9 ) \pm 3 5}{2 \cdot 1}

Separate the solutions

m_{1} = \frac{- ( - 9 ) + 3 5}{2 \cdot 1}, m_{2} = \frac{- ( - 9 ) - 3 5}{2 \cdot 1}

m = \frac{- ( - 9 ) + 3 5}{2 \cdot 1} : \frac{9 + 3 5}{2}

m = \frac{- ( - 9 ) - 3 5}{2 \cdot 1} : \frac{9 - 3 5}{2}

The solutions to the quadratic equation are:

m = \frac{9 + 3 5}{2}, m = \frac{9 - 3 5}{2}

7 u^{2} + 2 u - 15 = 0

3 x^{2} - 6 x + 17

x, y^{2} x - x^{2} y = y - 2 x

48 - (10 - 3 + x^{2}) + 2 xx = 4

- x^{2} - 3 x = 4
