Question

13) The coefficient of x 2in the polynomial is
a)^ 3 8; b) 8 c) 9 d) 3​

Answer 1

Answer:

Step-by-step explanation:The coefficient of a variable term is the constant number that multiplies by the variable. In other words, the coefficient is the number that stands in front of the variable when the term is simplified.

For −3x2 , the coefficient of x2 is −3 , because the −3 stands in front of the x2 . This indicates that −3x2 means −3∗x2 , i.e. the −3 multiplies by the x2 .

But if you want to find the coefficient of just x , we will re-write −3x2 as −3x2+0x+0 .

The number that multiplies by x (not x2 ) is 0 , as the x term is 0x . Therefore the coefficient of x is 0 .
