5 x^{2} - 20 x = 60

x = 6, x = - 2

Solution steps

5 x^{2} - 20 x = 60

Move

60

to the left side

5 x^{2} - 20 x - 60 = 0

Solve with the quadratic formula

x_{1, 2} = \frac{- ( - 20 ) \pm ( - 20 ) ^{2} - 4 \cdot 5 ( - 60 )}{2 \cdot 5}

(- 20)^{2} - 4 \cdot 5 (- 60) = 40

x_{1, 2} = \frac{- ( - 20 ) \pm 40}{2 \cdot 5}

Separate the solutions

x_{1} = \frac{- ( - 20 ) + 40}{2 \cdot 5}, x_{2} = \frac{- ( - 20 ) - 40}{2 \cdot 5}

x = \frac{- ( - 20 ) + 40}{2 \cdot 5} : 6

x = \frac{- ( - 20 ) - 40}{2 \cdot 5} : - 2

The solutions to the quadratic equation are:

x = 6, x = - 2

x^{2} + 12 x - 6 = 5

x (6 + x) - 2 (x + 1) - 5 x = 4

(x + 9)^{2} = 16

y, 36 x^{2} + 25 y^{2} = 900

x^{2} - 2 x - 35 = 0
