2sqrt(3)sec(x)+4=0

23 sec (x) + 4 = 0

x = \frac{5 π}{6} + 2 πn, x = \frac{7 π}{6} + 2 πn

Degrees

x = 15 0^{\circ} + 36 0^{\circ} n, x = 21 0^{\circ} + 36 0^{\circ} n

Solution steps

23 sec (x) + 4 = 0

Move

4

to the right side

23 sec (x) + 4 = 0

Subtract

4

from both sides

23 sec (x) + 4 - 4 = 0 - 4

Simplify

23 sec (x) = - 4

23 sec (x) = - 4

Divide both sides by

23

23 sec (x) = - 4

Divide both sides by

23

\frac{2 3 sec ( x )}{2 3} = \frac{- 4}{2 3}

Simplify

\frac{2 3 sec ( x )}{2 3} = \frac{- 4}{2 3}

Simplify

\frac{2 3 sec ( x )}{2 3} : sec (x)

\frac{2 3 sec ( x )}{2 3}

Divide the numbers:

\frac{2}{2} = 1

= \frac{3 sec ( x )}{3}

Cancel the common factor:

3

= sec (x)

Simplify

\frac{- 4}{2 3} : - \frac{2 3}{3}

\frac{- 4}{2 3}

Apply the fraction rule:

\frac{- a}{b} = - \frac{a}{b}

= - \frac{4}{2 3}

Divide the numbers:

\frac{4}{2} = 2

= - \frac{2}{3}

Rationalize

- \frac{2}{3} : - \frac{2 3}{3}

- \frac{2}{3}

Multiply by the conjugate

\frac{3}{3}

= - \frac{2 3}{3 3}

33 = 3

33

Apply radical rule:

a a = a

33 = 3

= 3

= - \frac{2 3}{3}

= - \frac{2 3}{3}

sec (x) = - \frac{2 3}{3}

sec (x) = - \frac{2 3}{3}

sec (x) = - \frac{2 3}{3}
