x^{2} - 7 x = 30

x = 10, x = - 3

Solution steps

x^{2} - 7 x = 30

Move

30

to the left side

x^{2} - 7 x - 30 = 0

Solve with the quadratic formula

x_{1, 2} = \frac{- ( - 7 ) \pm ( - 7 ) ^{2} - 4 \cdot 1 \cdot ( - 30 )}{2 \cdot 1}

(- 7)^{2} - 4 \cdot 1 \cdot (- 30) = 13

x_{1, 2} = \frac{- ( - 7 ) \pm 13}{2 \cdot 1}

Separate the solutions

x_{1} = \frac{- ( - 7 ) + 13}{2 \cdot 1}, x_{2} = \frac{- ( - 7 ) - 13}{2 \cdot 1}

x = \frac{- ( - 7 ) + 13}{2 \cdot 1} : 10

x = \frac{- ( - 7 ) - 13}{2 \cdot 1} : - 3

The solutions to the quadratic equation are:

x = 10, x = - 3

\frac{3}{4} (2 x - 1) - \frac{1}{5} (5 - 2 x) = - \frac{55}{12}

x^{2} + 4 x + 36 = 0
