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

x = 6, x = - 2

Solution steps

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

- 12 x^{2} + 48 x - 36 = 0

y, y^{2} = x^{4} (1 - x^{2})

3 y^{2} = 432

3 = \frac{5}{2} (x - 3 - 0.5)^{2}

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