10 x^{2} - 30 = - 20 x

x = 1, x = - 3

Solution steps

10 x^{2} - 30 = - 20 x

Move

20 x

to the left side

10 x^{2} - 30 + 20 x = 0

Write in the standard form

a x^{2} + b x + c = 0

10 x^{2} + 20 x - 30 = 0

Solve with the quadratic formula

x_{1, 2} = \frac{- 20 \pm 2 0 ^{2} - 4 \cdot 10 ( - 30 )}{2 \cdot 10}

2 0^{2} - 4 \cdot 10 (- 30) = 40

x_{1, 2} = \frac{- 20 \pm 40}{2 \cdot 10}

Separate the solutions

x_{1} = \frac{- 20 + 40}{2 \cdot 10}, x_{2} = \frac{- 20 - 40}{2 \cdot 10}

x = \frac{- 20 + 40}{2 \cdot 10} : 1

x = \frac{- 20 - 40}{2 \cdot 10} : - 3

The solutions to the quadratic equation are:

x = 1, x = - 3

3 x^{2} + 2 x = 5

\frac{n ( n - 3 )}{2} = n

\frac{n ( n - 3 )}{2} = 9

(x - 5) (x + 2) = 12

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