Question

find the value of k (x-3)is a factor of p(x)=2x3-5x2+3x+k​

Answer 1

Answer:

x-3=0 then x=3 value of k=-52×3-5×2+3×3+k =06-10+9+k =05+k =0k =-5

Answer 2

Answer:

let x-3=0

x= 3

put the value of x in p(x)

2x³-5x²+3x+k=0

2(3)³-5(3)²+3(3)+k=0

2×27-5×9+9+k=0

54-45-9+k=0

54-54+k=0

0+k=0

k=0
