x^{2} - 7 x - 638 = 0

x = 29, x = - 22

Solution steps

x^{2} - 7 x - 638 = 0

Solve with the quadratic formula

x_{1, 2} = \frac{- ( - 7 ) \pm ( - 7 ) ^{2} - 4 \cdot 1 \cdot ( - 638 )}{2 \cdot 1}

(- 7)^{2} - 4 \cdot 1 \cdot (- 638) = 51

x_{1, 2} = \frac{- ( - 7 ) \pm 51}{2 \cdot 1}

Separate the solutions

x_{1} = \frac{- ( - 7 ) + 51}{2 \cdot 1}, x_{2} = \frac{- ( - 7 ) - 51}{2 \cdot 1}

x = \frac{- ( - 7 ) + 51}{2 \cdot 1} : 29

x = \frac{- ( - 7 ) - 51}{2 \cdot 1} : - 22

The solutions to the quadratic equation are:

x = 29, x = - 22

x, 6 x y^{2} = - 12 x^{2} y

8 x^{2} + 6 x = 4

x, f (x - 2) = x^{2} - 3 x + 4

2 x^{2} + 3 x - 3 = 1

5 x^{2} - 9 x - 10 = 0
