6 x^{2} + 21 = 0

x = \frac{7}{2} i, x = - \frac{7}{2} i

Solution steps

6 x^{2} + 21 = 0

Move

21

to the right side

6 x^{2} = - 21

Divide both sides by

6

x^{2} = - \frac{7}{2}

For

x^{2} = f (a)

the solutions are

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

x = - \frac{7}{2}, x = - - \frac{7}{2}

- \frac{7}{2} = \frac{7}{2} i

- - \frac{7}{2} = - \frac{7}{2} i

x = \frac{7}{2} i, x = - \frac{7}{2} i

∣ 2 x + 3 ∣ < 7

\frac{3 y}{4} = 15

\frac{( 2 x ^{2} )}{2} x + \frac{( 3 y ^{2} )}{y}

5 = \frac{1}{5} x - 3

15 = \frac{b}{15}
