Question

Write the coefficient of x2 in the following: a) x2-x + 4 b) x3 - 3x2 + 5x2 - 4

Answer 1

Step-by-step explanation:

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

Answer 2

ANSWER:-

➣

• Given:-

a.] $\longrightarrow{x^2 - x + 4}$

• Coefficient of $x^2$ in this equation is:

$\bf{\longrightarrow{1}}$

b.] $\longrightarrow{x^3 - 3 x^2 + 5 x - 4}$

• Coefficient of $x^2$ in this equation is:

$\bf{\longrightarrow{3}}$

Note:-

The 2nd equation has some corrections:-

• ${\bf{x^3 - 3 x^2 + 5 x - 4}}$
