7 a^{2} + 35 = 0

a = 5 i, a = - 5 i

Solution steps

7 a^{2} + 35 = 0

Move

35

to the right side

7 a^{2} = - 35

Divide both sides by

7

a^{2} = - 5

For

x^{2} = f (a)

the solutions are

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

a = - 5, a = - - 5

- 5 = 5 i

- - 5 = - 5 i

a = 5 i, a = - 5 i

4 x^{2} - 6 x = - 2

x^{2} - 2 x - 8 = 0

12 x^{2} - 42 x + 36 = 0

x, 5 x^{2} + 5 y^{2} + 6 x y = 8

3 x^{2} - 19 x + 6 = 0
