B^{2} - 81 = 0

B = 9, B = - 9

Solution steps

B^{2} - 81 = 0

Move

81

to the right side

B^{2} = 81

For

x^{2} = f (a)

the solutions are

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

B = 81, B = - 81

81 = 9

- 81 = - 9

B = 9, B = - 9

x^{2} - 3 x + 2

x^{2} + 5 x + c

x^{2} + 3 x = - 4 x

s^{2} + 8 s + 16

x^{2} + 5 x + \frac{5}{4} = 0
