x (x - 5) = 750

x = 30, x = - 25

Solution steps

x (x - 5) = 750

Expand

x (x - 5) : x^{2} - 5 x

x^{2} - 5 x = 750

Move

750

to the left side

x^{2} - 5 x - 750 = 0

Solve with the quadratic formula

x_{1, 2} = \frac{- ( - 5 ) \pm ( - 5 ) ^{2} - 4 \cdot 1 \cdot ( - 750 )}{2 \cdot 1}

(- 5)^{2} - 4 \cdot 1 \cdot (- 750) = 55

x_{1, 2} = \frac{- ( - 5 ) \pm 55}{2 \cdot 1}

Separate the solutions

x_{1} = \frac{- ( - 5 ) + 55}{2 \cdot 1}, x_{2} = \frac{- ( - 5 ) - 55}{2 \cdot 1}

x = \frac{- ( - 5 ) + 55}{2 \cdot 1} : 30

x = \frac{- ( - 5 ) - 55}{2 \cdot 1} : - 25

The solutions to the quadratic equation are:

x = 30, x = - 25

1 5^{2} + 1 1^{2} = x^{2}

3 u^{2} + 7 u - 6 = 0

5 x^{2} + 215 x + 3 = 0

x^{2} - 4 x + 2 = 0

x, y = a (x - p)^{2} + q
