What is one value that makes the fraction (x^2 + 11x + 30) / (4x + 44x^2 + 120x) Undefined?

-31/11

Step-by-step explanation:

To get the value they makes the fraction undefined, we shall need to equate the denominator to zero

Hence;

4x + 44x^2 + 120x

Divide through be x

4 + 44x + 120 = 0

44x = - 124

x = - 124/44

x = - 62/22

x = - 31/11
