5 x^{2} - 5 x - 30 = 0

x = 3, x = - 2

Solution steps

5 x^{2} - 5 x - 30 = 0

Solve with the quadratic formula

x_{1, 2} = \frac{- ( - 5 ) \pm ( - 5 ) ^{2} - 4 \cdot 5 ( - 30 )}{2 \cdot 5}

(- 5)^{2} - 4 \cdot 5 (- 30) = 25

x_{1, 2} = \frac{- ( - 5 ) \pm 25}{2 \cdot 5}

Separate the solutions

x_{1} = \frac{- ( - 5 ) + 25}{2 \cdot 5}, x_{2} = \frac{- ( - 5 ) - 25}{2 \cdot 5}

x = \frac{- ( - 5 ) + 25}{2 \cdot 5} : 3

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

The solutions to the quadratic equation are:

x = 3, x = - 2

x^{2} - 12 x - 28

3 x^{2} + 12 x + 81 = 15

2 x = x + 1

- \frac{( 2 ) ^{5}}{5} + \frac{13 ( 2 ) ^{3}}{3} - 36 (2)

3 lo g_{3} (2) - lo g_{3} (72)
