Question

(x+3) is a factor of x ki power 4 - xcube - 11xsquare - 11 + k

Answer 1

then u want the value of K the okay 

x = -3

81-(-27)-33+k = 0
81+27-33 +k = 0
108-33+k =0
75+k=0
  
    k = -75




hope its helpful

Answer 2

Hii friend,

(X+3) is a factor of the given polynomial.

X+3 = 0

X = -3

P(X) = X⁴-X³-11X²-11X+K

P(-3) = (-3)⁴ - (-3)³ - 11 × (-3)² - 11 × -3 + K

= 81 - (-27) - 11 × 9 +33 + K

= 81 + 27 -99 + 33 + K

= 141 - 99 + K

= 42-K

K = 42


HOPE IT WILL HELP YOU..... :-)
