x^{2} - 13 x = 30

x = 15, x = - 2

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 ( - 13 ) ^{2} - 4 \cdot 1 \cdot ( - 30 )}{2 \cdot 1}

(- 13)^{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} : 15

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

The solutions to the quadratic equation are:

x = 15, x = - 2

x^{2} - 6 (x - 1) = 7 (1 - x)

x^{2} - x = - 3 x + 3

x, x (x - c) = a

4 x^{2} + 13 x = 12

2 (x + 3)^{2} + 4 = 0
