Answer 2

Question :

Find the value of k,when x²-kx+7 is divided by (x+2)

Answer :

g(x) = x + 2

→ x + 2 = 0

→ x = 0 - 2

.°. x = -2

p(x) = x²- kx + 7

→ x²- kx + 7 = 0

Putting the value of x

→ (-2)² - k(-2) + 7 = 0

→ 4 + 2k + 7 = 0

→ 11 + 2k = 0

→ 2k = 0 - 11

→ 2k = -11

→ k = -11/2

.°. The value of k is -11/2...
