(3 x - 1)^{2} + x (x - 3) = - 1

x = \frac{1}{2}, x = \frac{2}{5}

Decimal Notation

x = 0.5, x = 0.4

Solution steps

(3 x - 1)^{2} + x (x - 3) = - 1

Expand

(3 x - 1)^{2} + x (x - 3) : 10 x^{2} - 9 x + 1

10 x^{2} - 9 x + 1 = - 1

Move

1

to the left side

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

Solve with the quadratic formula

x_{1, 2} = \frac{- ( - 9 ) \pm ( - 9 ) ^{2} - 4 \cdot 10 \cdot 2}{2 \cdot 10}

(- 9)^{2} - 4 \cdot 10 \cdot 2 = 1

x_{1, 2} = \frac{- ( - 9 ) \pm 1}{2 \cdot 10}

Separate the solutions

x_{1} = \frac{- ( - 9 ) + 1}{2 \cdot 10}, x_{2} = \frac{- ( - 9 ) - 1}{2 \cdot 10}

x = \frac{- ( - 9 ) + 1}{2 \cdot 10} : \frac{1}{2}

x = \frac{- ( - 9 ) - 1}{2 \cdot 10} : \frac{2}{5}

The solutions to the quadratic equation are:

x = \frac{1}{2}, x = \frac{2}{5}

5 t^{2} + 3 t - 2 = 0

25 x^{2} + 30 x + 12

t, h = v t - g t^{2}

9 x^{2} - 12 x - 14 = 0

x^{2} - 13 x + 1 = - 9 x + 6
