If x^2 – 3x = 18, then one possible value of x – 4 =
Choose the correct choice from the following choices
A) - 9
B) - 5
C) - 3
D) - 1
E) 2

Rationale: x ^ 2 – 3 x = 18 i . e . x ^ 2 – 3 x - 18 = 0 i . e . x ^ 2 – 6 x + 3 x - 18 = 0 i . e . ( x - 6 ) ( x + 3 ) = 0 i . e . x = 6 or - 3 i . e . x - 4 = 6 - 4 or - 3 - 4 i . e . x - 4 = 2 or - 7 answer : option e
Answer: E
