9 x^{2} - 34 x + 21 = 0

x = 3, x = \frac{7}{9}

Decimal Notation

x = 3, x = 0.77777 \dots

Solution steps

9 x^{2} - 34 x + 21 = 0

Solve with the quadratic formula

x_{1, 2} = \frac{- ( - 34 ) \pm ( - 34 ) ^{2} - 4 \cdot 9 \cdot 21}{2 \cdot 9}

(- 34)^{2} - 4 \cdot 9 \cdot 21 = 20

x_{1, 2} = \frac{- ( - 34 ) \pm 20}{2 \cdot 9}

Separate the solutions

x_{1} = \frac{- ( - 34 ) + 20}{2 \cdot 9}, x_{2} = \frac{- ( - 34 ) - 20}{2 \cdot 9}

x = \frac{- ( - 34 ) + 20}{2 \cdot 9} : 3

x = \frac{- ( - 34 ) - 20}{2 \cdot 9} : \frac{7}{9}

The solutions to the quadratic equation are:

x = 3, x = \frac{7}{9}

x^{2} - 8 x + 7 = 0

x^{2} - 65 x + 946 = 0

25 x^{2} - 30 = 0

(y^{2} - 3) 2 + 2 (y^{2} - 3) - 48 = 0

- 0.25 x^{2} - 83 x + 1032 = 0
