Question

find the value of k if x-3 is a factor of x3-4xwraist power2+x+k​

Answer 1

Answer:

if x-k is a factor then after putting x=k we get the solution of the equation Step-by-step explanation:

if x-k is a factor ⇒x=k

now given euation is x³-kx²+x+2=0

after put x=k

we get k³-k×k²+k+2=0

⇒k+2=0

⇒k=-2
