x^{2} + 13 x = 30

x = 2, x = - 15

Solution steps

x^{2} + 13 x = 30

Move

30

to the left side

x^{2} + 13 x - 30 = 0

Solve with the quadratic formula

x_{1, 2} = \frac{- 13 \pm 1 3 ^{2} - 4 \cdot 1 \cdot ( - 30 )}{2 \cdot 1}

1 3^{2} - 4 \cdot 1 \cdot (- 30) = 17

x_{1, 2} = \frac{- 13 \pm 17}{2 \cdot 1}

Separate the solutions

x_{1} = \frac{- 13 + 17}{2 \cdot 1}, x_{2} = \frac{- 13 - 17}{2 \cdot 1}

x = \frac{- 13 + 17}{2 \cdot 1} : 2

x = \frac{- 13 - 17}{2 \cdot 1} : - 15

The solutions to the quadratic equation are:

x = 2, x = - 15

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

2 x^{2} + 16 x + 11

12 x^{2} - 60 x + 48 = 0

- x^{2} + 10 x - 15 = 1

y, - 5 x^{2} y - 3 y - 6 y^{2} = 3 x
