2 a^{2} + 98 = 0

a = 7 i, a = - 7 i

Solution steps

2 a^{2} + 98 = 0

Move

98

to the right side

2 a^{2} = - 98

Divide both sides by

2

a^{2} = - 49

For

x^{2} = f (a)

the solutions are

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

a = - 49, a = - - 49

- 49 = 7 i

- - 49 = - 7 i

a = 7 i, a = - 7 i

v^{2} - 2 v - 15 = 0

22 - 2

\frac{8}{89}

23 - 2

- 2 i \cdot 2 i
