Question

find the value of k if (x-3) is a factor of p(x) equals 2x cube minus 5
x square + 3 X + k

Answer 1

p(x)=2x³-5x²+3x+k
if (x-3)is a factor of p(x)
then ,3 is the zero of the polynomial
∴x=3
p(3)=0
⇒2×3³-5×3²+3×3+k=0
⇒54-45+9+k=0
⇒18+k=0
⇒k=-18
∴the value of K is -18

Hope it helps you :-)

Answer 2

Answer:

-18 is the k of the polynomial
