Question

find whether 5+3x is a factor of 3x^2+11x+10

Answer 1

Answer:

Step-by-step explanation:

to check whether 5 + 3x is factor or not

we use 5+3x =0

x= -5/3

3x² +11x +10

3*25/9 + 11*(-5/3) +10

25/3-55/3+10==> 0

So 5 + 3x is factor of given polynomial

Answer 2

Step-by-step explanation:

5+3x=o

thus x=-5/3

Substitute x in the equation and if you will get answer as 0, then it is a factor
