5 (x - 9)^{2} = 20

x = 11, x = 7

Solution steps

5 (x - 9)^{2} = 20

Divide both sides by

5

(x - 9)^{2} = 4

For

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

the solutions are

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

Solve

x - 9 = 4 : x = 11

Solve

x - 9 = - 4 : x = 7

The solutions to the quadratic equation are:

x = 11, x = 7

y, x^{3} + 4 x^{2} + x y^{2} - 4 y^{2} = 0

3 y^{2} - 11 y + 10 = 0

x, x^{2} + y^{2} + 3 x + y + 10 = 0

a, a^{2} + 7^{2} = 1 6^{2}

2 (x + 3)^{2} = 18
