(5 y + 9)^{2} = 80

y = \frac{4 5 - 9}{5}, y = \frac{- 4 5 - 9}{5}

Decimal Notation

y = - 0.01114 \dots, y = - 3.58885 \dots

Solution steps

(5 y + 9)^{2} = 80

For

(g (x))^{2} = f (a)

the solutions are

g (x) = f (a), - f (a)

Solve

5 y + 9 = 80 : y = \frac{4 5 - 9}{5}

Solve

5 y + 9 = - 80 : y = \frac{- 4 5 - 9}{5}

The solutions to the quadratic equation are:

y = \frac{4 5 - 9}{5}, y = \frac{- 4 5 - 9}{5}

2 y^{2} - 8 y = - 5

d^{2} + 4 d - 140 = 0

x^{2} = - 16

z^{2} + 16 z + 89 = 0

x (x - 9) = 1
