220 - (16.5 - 2 x)^{2} = 99.9

x = 2.77049 \dots, x = 13.72950 \dots

Solution steps

220 - (16.5 - 2 x)^{2} = 99.9

Move

220

to the right side

- (16.5 - 2 x)^{2} = - 120.1

Divide both sides by

- 1

(16.5 - 2 x)^{2} = 120.1

For

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

the solutions are

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

Solve

16.5 - 2 x = 120.1 : x = 2.77049 \dots

Solve

16.5 - 2 x = - 120.1 : x = 13.72950 \dots

The solutions to the quadratic equation are:

x = 2.77049 \dots, x = 13.72950 \dots

5 x^{2} + 20 x

8 z^{2} - 3 z - 2 = 0

x (2 x - 9) = - 10

m^{2} + 12 m = 52
