6 x^{2} + 56 = - 40

x = 4 i, x = - 4 i

Solution steps

6 x^{2} + 56 = - 40

Move

56

to the right side

6 x^{2} = - 96

Divide both sides by

6

x^{2} = - 16

For

x^{2} = f (a)

the solutions are

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

x = - 16, x = - - 16

- 16 = 4 i

- - 16 = - 4 i

x = 4 i, x = - 4 i

\frac{7}{9} + \frac{5}{6} \cdot \frac{1}{3}

4 r^{2} = 100

12 x^{6} - 3 x^{2}

- 4 x^{3} \cdot 2 y^{- 2} \cdot 5 y^{5} \cdot x^{- 8}

1 0^{2}
