v^{2} - 81 = 0

v = 9, v = - 9

Solution steps

v^{2} - 81 = 0

Move

81

to the right side

v^{2} = 81

For

x^{2} = f (a)

the solutions are

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

v = 81, v = - 81

81 = 9

- 81 = - 9

v = 9, v = - 9

r, r^{2} + r - 42 = 0

x, x^{2} - 12 x + 27 = 0

x^{2} - 9 x - 10 = 2 x + 10

x^{2} - 14 x + 30 = 0

3 x^{2} - 12 x + 8 = 0
