Solve for x
2 + x^2 = 18​

16

Step-by-step explanation:

4 and -4

Step-by-step explanation:

To solve, just isolate x

2+x^2=18

subtract both sides of the equation by 2

x^2=16

find the square root of 16

(remember, no matter if a number is positive or negative, if it is squared, it automatically becomes positive)

to get:

x=4

and

x= -4

the transverse axis of a hyperbola is the line that contains the two vertices and the two focuses.

in this example (hyperbola of equation x^2/2 - y^2/4 = 1), the transverse axis is the  x-axis  .
