2 x^{2} + 14 = - 84

x = 7 i, x = - 7 i

Solution steps

2 x^{2} + 14 = - 84

Move

14

to the right side

2 x^{2} = - 98

Divide both sides by

2

x^{2} = - 49

For

x^{2} = f (a)

the solutions are

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

x = - 49, x = - - 49

- 49 = 7 i

- - 49 = - 7 i

x = 7 i, x = - 7 i

x^{2} - 6 x + 40

y^{2} - 2 y - 3 = 0

(x - 1)^{2} = 100

1 7^{2} = 8^{2} + x^{2}

x, x^{2} + x + 1 = 0
