Question

consider the expression x (m2−1) + 3x m 2 , where m is a constant. For what value of m, will the expression be a cubic polynomial​

Answer 1

Answer:

Answer:

m=2

Step-by-step explanation:

we have a polynomial p(x) x^m²-1 + 3x^m/2

In order to make it cubic we need degree 3 .

So which means

power of x =3

m²-1=3

m²=3+1=4 Therefore, m=2,-2

-2 is rejected as in 3x^m/2 If we put m=-2 then it will become -2/2 = -1 which result into no polynomial condition so its rejected. and 2 is the answer

Answer 2

this is the answer
