Which is the largest negative integer which satisfies(x^2 – 1)/(x – 2)(x – 3)?(a) -4(b) -3(c) -1(d) -2The question was posed to me in class test.My question comes from Applications of Quadratic Equations topic in section Complex Numbers and Quadratic Equations of Mathematics – Class 11

Answer»

Correct answer is (d) -2

Explanation: By WAVY curve METHOD

(x^2 – 1)/(x – 2)(x – 3) > 0

So, x = -1, 1, 2, 3

Thus, x €(-∞, -1) ∪ (1, 2) ∪ (3, ∞)

THEREFORE, the largest negative integer is -2.
