Answer» Given polynomial x^2 - 5x + 4 If (x - 3) is factor of polynomial then for x = 3 given equation will be equal to 0 Put x= 3 in given equation of polynomial33 - 53 + 4 = 9 - 15 + 4= 13 - 15 = - 2 Therefore 2 should be added to given polynomial. thanks

Answer»

Given polynomial x^2 - 5x + 4

If (x - 3) is factor of polynomial then for x = 3 given equation will be equal to 0

Put x= 3 in given equation of polynomial3*3 - 5*3 + 4 = 9 - 15 + 4= 13 - 15 = - 2

Therefore 2 should be added to given polynomial.
