1.	If (x+2) is factor of xki power4+xki power3-xki power2-2x+k find the value of 'k'
Answer» Answer: k=-8 Step-by-step explanation: we know if x+2 is factor of x^4+x^3-x^2-2x+k x=-2 will be a solution of the equation SUB x=-2 (-2)^4+(-2)^3-(-2)^2-2*-2+k=0 =>16-8-4+4+k=0 k+8=0 therefore k=-8

If (x+2) is factor of xki power4+xki power3-xki power2-2x+k find the value of 'k'

Answer»

Answer:

k=-8

Step-by-step explanation:

we know if x+2 is factor of x^4+x^3-x^2-2x+k

x=-2 will be a solution of the equation

SUB x=-2

(-2)^4+(-2)^3-(-2)^2-2*-2+k=0

=>16-8-4+4+k=0

k+8=0

therefore k=-8
