x^{2} - x = 72

x = 9, x = - 8

Solution steps

x^{2} - x = 72

Move

72

to the left side

x^{2} - x - 72 = 0

Solve with the quadratic formula

x_{1, 2} = \frac{- ( - 1 ) \pm ( - 1 ) ^{2} - 4 \cdot 1 \cdot ( - 72 )}{2 \cdot 1}

(- 1)^{2} - 4 \cdot 1 \cdot (- 72) = 17

x_{1, 2} = \frac{- ( - 1 ) \pm 17}{2 \cdot 1}

Separate the solutions

x_{1} = \frac{- ( - 1 ) + 17}{2 \cdot 1}, x_{2} = \frac{- ( - 1 ) - 17}{2 \cdot 1}

x = \frac{- ( - 1 ) + 17}{2 \cdot 1} : 9

x = \frac{- ( - 1 ) - 17}{2 \cdot 1} : - 8

The solutions to the quadratic equation are:

x = 9, x = - 8

x^{3} - 4 x + 15

\frac{x ^{5}}{x ^{7}}

20 x^{2} + 55 x + 30

0 = - 4.9 t^{2} + 346 t + 290
