Question

If ( x - 1), is the factor of the
polynomial 3x2+ mx, then find
the value of m ?​

Answer 1

Step-by-step explanation:

Consider the given polynomials x−1,3x

2

+mx

Given that x−1 is factor of 3x

2

+mx

So,

x−1=0

x=1

x=1 will satisfied 3x

2

+mx

Now,

3x

2

+mx=1

3.1

2

+m×1=0

3+m=0

m=−3

Hence this is the answer .
