74 - 2 x^{2} = 84

x = 5 i, x = - 5 i

Solution steps

74 - 2 x^{2} = 84

Move

74

to the right side

- 2 x^{2} = 10

Divide both sides by

- 2

x^{2} = - 5

For

x^{2} = f (a)

the solutions are

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

x = - 5, x = - - 5

- 5 = 5 i

- - 5 = - 5 i

x = 5 i, x = - 5 i

9 x^{2} - 5 x (\frac{28 x}{33}) + 7 (\frac{28 x}{33})^{2} = 120

(x + 5) x = 0

(x^{2} - 4 x + 4) - \frac{( 20 x + 8 ) ^{2}}{225} = 4

u, v (2 u v^{2} - 3) d u + (3 u^{2} v^{2} - 3 + 4 v) d v = 0

a^{2} + 8 a - 9 = 0
