- 3 w^{2} - 78 = 138

w = 62 i, w = - 62 i

Solution steps

- 3 w^{2} - 78 = 138

Move

78

to the right side

- 3 w^{2} = 216

Divide both sides by

- 3

w^{2} = - 72

For

x^{2} = f (a)

the solutions are

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

w = - 72, w = - - 72

- 72 = 62 i

- - 72 = - 62 i

w = 62 i, w = - 62 i

v^{2} = - 9

x^{2} - 3 x - 27 = 0

3 x^{2} - 16 x + 13 = - 4

1 3^{2} + 1 2^{2} = x^{2}

0 = x^{2} - 13 x + 36
