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

x = 15, x = - 2

Solution steps

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

15 x^{2} + 7 x - 2 = 0

25 (x + 2)^{2} = (x - 7)^{2} - 81

x^{2} - 3 x - 44 = - 3 x + 5

a, x^{2} + y^{2} = a^{2}

x^{2} + 2 x + 5
