- (3x + 2) (2x - 5) = ax² + kx + n. What is the value of a - n + k ?
Question 1:
(3x + 2) (2x - 5) = ax² + kx + n. What is the value of a - n + k ? A. 4
B. 1
C. 5
Feedback (3x + 2) (2x - 5) = ax2+kx+n ...............(1)
But (3x + 2)(2x - 5) = 6x2−11x−10........(2)
so by comparing (1) & (2),
we get a= 6, k= -11 , n= -10
(a - n + k) = 6 + 10 - 11 = 5.
