If one root of the equation 2x^2 + 3x – k = 0 is 4, what is the value of k? Choose the most appropriate option: A) 35 B) 40 C) 44 D) 45 E) 56

Rationale: "we just enter this root into the equation in order to recieve an equation to find the answer ! 2 * 4 ^ 2 + 3 * 4 - k = 0 k = 32 + 12 = 44 the answer is c"
Answer: C
