2 x (2 x + 10) = - 25

x = - \frac{5}{2}

Decimal Notation

x = - 2.5

Solution steps

2 x (2 x + 10) = - 25

Expand

2 x (2 x + 10) : 4 x^{2} + 20 x

4 x^{2} + 20 x = - 25

Move

25

to the left side

4 x^{2} + 20 x + 25 = 0

Solve with the quadratic formula

x_{1, 2} = \frac{- 20 \pm 2 0 ^{2} - 4 \cdot 4 \cdot 25}{2 \cdot 4}

2 0^{2} - 4 \cdot 4 \cdot 25 = 0

x_{1, 2} = \frac{- 20 \pm 0}{2 \cdot 4}

x = \frac{- 20}{2 \cdot 4}

\frac{- 20}{2 \cdot 4} = - \frac{5}{2}

x = - \frac{5}{2}

The solution to the quadratic equation is:

x = - \frac{5}{2}

3 x^{2} - 5 = - 4 x

2 x^{2} + 7 x + 12 = 0

y, (c y^{2}) (4 y d) = - 20 y^{3}

(x) = x^{2} - 1

p^{2} - 8 p + 12 = 0
