20 \cdot 5 - 19 = r^{2}

r = 9, r = - 9

Solution steps

20 \cdot 5 - 19 = r^{2}

Switch sides

r^{2} = 20 \cdot 5 - 19

Simplify

20 \cdot 5 - 19 : 81

For

x^{2} = f (a)

the solutions are

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

r = 81, r = - 81

81 = 9

- 81 = - 9

r = 9, r = - 9

4 y^{2} + 15 y + 6 = 4 y

p^{2} + 0.2 p - 0.96 = 0

v^{2} = 256

(19 x - 2 x) (35 - 2 x) = 465

2 (3 x)^{2} = 162
