3 y^{2} - 6 y - 45 = 0

y = 5, y = - 3

Solution steps

3 y^{2} - 6 y - 45 = 0

Solve with the quadratic formula

y_{1, 2} = \frac{- ( - 6 ) \pm ( - 6 ) ^{2} - 4 \cdot 3 ( - 45 )}{2 \cdot 3}

(- 6)^{2} - 4 \cdot 3 (- 45) = 24

y_{1, 2} = \frac{- ( - 6 ) \pm 24}{2 \cdot 3}

Separate the solutions

y_{1} = \frac{- ( - 6 ) + 24}{2 \cdot 3}, y_{2} = \frac{- ( - 6 ) - 24}{2 \cdot 3}

y = \frac{- ( - 6 ) + 24}{2 \cdot 3} : 5

y = \frac{- ( - 6 ) - 24}{2 \cdot 3} : - 3

The solutions to the quadratic equation are:

y = 5, y = - 3

6 x^{2} - 30 x + 24

(- \frac{4}{5})^{- 4}

x^{7} - 1

5 x + 4 = 19
