x^{2} - 17 x = - 72

x = 9, x = 8

Solution steps

x^{2} - 17 x = - 72

Move

72

to the left side

x^{2} - 17 x + 72 = 0

Solve with the quadratic formula

x_{1, 2} = \frac{- ( - 17 ) \pm ( - 17 ) ^{2} - 4 \cdot 1 \cdot 72}{2 \cdot 1}

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

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

Separate the solutions

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

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

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

The solutions to the quadratic equation are:

x = 9, x = 8

10 x^{2} + 4 x + 77 = 9

0 = (x - 11) (x - 1)

x^{2} - 12 x + 37

a^{2} + 12 a + 27 = 0

3 x^{2} - 7 = 7 x - 1
