(r - 5)^{2} = 40

r = 210 + 5, r = - 210 + 5

Solution steps

(r - 5)^{2} = 40

For

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

the solutions are

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

Solve

r - 5 = 40 : r = 210 + 5

Solve

r - 5 = - 40 : r = - 210 + 5

The solutions to the quadratic equation are:

r = 210 + 5, r = - 210 + 5

2 x^{2} - x - 10 = 0

2 x^{2} + 7 x + 6 = 0

x^{2} + 3 x + 30 = 0

(x - 7) (5 x + 8) = 0

- \frac{1}{500} (x - 100)^{2} + 20 = 0
