Find the zero(s) of the rational expression below. fraction numerator 5 x squared plus 26 x plus 24 over denominator 3 x squared plus 10 x minus 8 end fraction

For this case we have the following rational expression:
 
 What we must do for this case, is to factor the numerator and the denominator.
 We have then:
 
 Then, canceling similar terms we have:
 
 Then, the function is not defined for the values that make the denominator zero.
 We have then:
 
 
 And on the other hand, a zero of the function is:
 
 
 
 a zero of the function is:
 
 the function is not defined for the value:
