If one root of the equation 2x^2 + 3x – k = 0 is 5, what is the value of k?	Choose the correct choice
A) 65
B) 79
C) 68
D) 87
E) 90

Rationale: "we just enter this root into the equation in order to recieve an equation to find the answer ! 2 * 5 ^ 2 + 3 * 5 - k = 0 k = 50 + 15 = 65 the answer is a"
Answer: A
