Question:-

Write the coefficient of x2in the following:

• a)x2−x+4
• b)x3−3x2+5x2−4

____________________

Answer:-

• a) Coefficient of x^2 is 1. This is because x^2 is not having any number so 1 is it's coefficient
• b) Coefficient of x^2 is 3

How to find coefficient of any variable

• First see in question , which coefficient of variable is needed.
• Then see what number is given in side of variable , for which they need coefficient
• If any number is in minus or in plus that number is called to be an term not coefficient.
• If any number is in multiple or in fraction form present in side of variable for that they need coefficient. So that number as well fraction is called to be coefficient .
