x^{2} - 15 x = 100

x = 20, x = - 5

Solution steps

x^{2} - 15 x = 100

Move

100

to the left side

x^{2} - 15 x - 100 = 0

Solve with the quadratic formula

x_{1, 2} = \frac{- ( - 15 ) \pm ( - 15 ) ^{2} - 4 \cdot 1 \cdot ( - 100 )}{2 \cdot 1}

(- 15)^{2} - 4 \cdot 1 \cdot (- 100) = 25

x_{1, 2} = \frac{- ( - 15 ) \pm 25}{2 \cdot 1}

Separate the solutions

x_{1} = \frac{- ( - 15 ) + 25}{2 \cdot 1}, x_{2} = \frac{- ( - 15 ) - 25}{2 \cdot 1}

x = \frac{- ( - 15 ) + 25}{2 \cdot 1} : 20

x = \frac{- ( - 15 ) - 25}{2 \cdot 1} : - 5

The solutions to the quadratic equation are:

x = 20, x = - 5

y, 4 x^{3} - 2 y^{2} + 14 x = 0

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

18 x^{2} + 25 x - 3 = 0

9^{2} + 2^{2} = x^{2}

(x + 4) (x + 6) = 0
