Find the values of x for which ( frac{1}{2x^2 – 13x +15} ) is not defined,

A.
5 or ( frac{3}{2} ) 
B.
1 or ( frac{15}{13} ) 
C.
2 or 15 
D.
13 or 15
Correct Answer: Option A
Explanation
The fraction is undefined when the denominator is equal to zero
(2x^2 – 13x + 15 = 0\
2x^2 – 3x – 10x + 15\
x(2x3)5(2x3) = 0\
(2x3)(x5)=0\
x = frac{3}{2} or x = 5)
