Answer:
7 and -7
Step-by-step explanation:
Correct question
Which shows all the values of x that make the rational expression 2x^2-72/5x^2-245 undefined
For the expression to be undefined, the denominator must be equal to zero
Hence 5x² - 245 =0
Add 245 to both sides
5x²-245+245 = 0+245
5x² = 245
x² = 245/5
x² = 49
x = ±√49
x =7 and -7
Hence the values of x that will make the function undefined are 7 and -7
