Q:

(3x + 2) (2x - 5) = ax² + kx + n. What is the value of a - n + k ?

A) 4	B) 1
C) 5	D) 3

Answer & Explanation Answer: C) 5

Explanation:

(3x + 2) (2x - 5) = $a x^{2} + k x + n$ ...............(1)

But (3x + 2)(2x - 5) = $6 x^{2} - 11 x - 10$ ........(2)

so by comparing (1) & (2),

we get a= 6, k= -11 , n= -10

(a - n + k) = 6 + 10 - 11 = 5.
