f^{2} - 63 = 81

f = 12, f = - 12

Solution steps

f^{2} - 63 = 81

Move

63

to the right side

f^{2} = 144

For

x^{2} = f (a)

the solutions are

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

f = 144, f = - 144

144 = 12

- 144 = - 12

f = 12, f = - 12

3 2 a - 3 2 b

18 x^{2} y - 42 x^{2} - 27 y + 63

3 x^{2} + 5 x

\frac{x}{2} = 60
