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

x = \frac{2}{5}, x = - \frac{4}{5}

Decimal

x = 0.4, x = - 0.8

Solution steps

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

Move

9

to the left side

25 x^{2} + 10 x - 8 = 0

Solve with the quadratic formula

x_{1, 2} = \frac{- 10 \pm 1 0 ^{2} - 4 \cdot 25 ( - 8 )}{2 \cdot 25}

1 0^{2} - 4 \cdot 25 (- 8) = 30

x_{1, 2} = \frac{- 10 \pm 30}{2 \cdot 25}

Separate the solutions

x_{1} = \frac{- 10 + 30}{2 \cdot 25}, x_{2} = \frac{- 10 - 30}{2 \cdot 25}

x = \frac{- 10 + 30}{2 \cdot 25} : \frac{2}{5}

x = \frac{- 10 - 30}{2 \cdot 25} : - \frac{4}{5}

The solutions to the quadratic equation are:

x = \frac{2}{5}, x = - \frac{4}{5}

x^{2} + 2 x - 5 = 75

625 x^{2} - 25 x = 0

X^{2} + 5 X + 6 = 0

2 s^{2} = 50

2 x^{2} + 7 x = 42 - x
