x≠−1

x≠1

x≠2

x≠3

x≠−3

x≠−2

The domain restrictions apply to rational expression are:

Solution:

Given rational expression is:

We have to find the domain restrictions apply to rational expression

From given,

Use the identity,

Therefore,

The rational expression is undefined when denominator is 0

From above, see the denominator (x + 3) and (x - 3)

When x = -3 and x = 3, the denominator becomes 0

Thus, domain restrictions are:

actually your concept is wrong

step-by-step explanation:

150% of x =300

150x=300×100

x=(300×100)÷150

x=200
