x^{2} - 6 x - 20 = 20

x = 10, x = - 4

Solution steps

x^{2} - 6 x - 20 = 20

Move

20

to the left side

x^{2} - 6 x - 40 = 0

Solve with the quadratic formula

x_{1, 2} = \frac{- ( - 6 ) \pm ( - 6 ) ^{2} - 4 \cdot 1 \cdot ( - 40 )}{2 \cdot 1}

(- 6)^{2} - 4 \cdot 1 \cdot (- 40) = 14

x_{1, 2} = \frac{- ( - 6 ) \pm 14}{2 \cdot 1}

Separate the solutions

x_{1} = \frac{- ( - 6 ) + 14}{2 \cdot 1}, x_{2} = \frac{- ( - 6 ) - 14}{2 \cdot 1}

x = \frac{- ( - 6 ) + 14}{2 \cdot 1} : 10

x = \frac{- ( - 6 ) - 14}{2 \cdot 1} : - 4

The solutions to the quadratic equation are:

x = 10, x = - 4

4 x^{2} - 3 x - 12 = 3 x^{2} - 6 x - 14

(x - 7)^{2} = - 9

3 x^{2} - 8 x - 16

25 x^{2} - 196 = 0

4 (x + 2)^{2} + 13 = 29
