Move the minus sign from the numerator to the front of the expression.
-(9p)/(p+4)
The domain of an expression is all real numbers except for the regions where the expression is undefined. This can occur where the denominator equals 0, a square root is less than 0, or a logarithm is less than or equal to 0. All of these are undefined and therefore are not part of the domain.
(p+4)=0
Solve the equation to find where the original expression is undefined.
p=-4
The domain of the rational expression is all real numbers except where the expression is undefined.
p(is not equal to)-4 (-infinite,-4) U (-4. infinite)
