Question

If x2 + kx + 6 = (x - 2) (x – 3) then the value of k is
A )5
B )6
C)-5
D)-6​

Answer 1

Answer:

-5

Step-by-step explanation:

x² + kx + 6 = (x-2) (x-3)

x² + kx + 6 = x² - 2x - 3x + 6

x² + kx + 6 = x² + (-5x) + 6

Therefore, k = -5

Answer 2

Answer:

-5

Step-by-step explanation:

${x}^{2} + kx + 6 = (x - 2)(x - 3)$

${x}^{2} + kx + 6 = {x}^{2} - 2x - 3x + 6$

${x}^{2} + kx + 6 = {x}^{2} - 5x + 6$

Hence k = -5
