Question

Write the coefficients of x2 in each of the following
(i) 2 + x2 + x

Answer 1

Answer:

The coefficient of x² in the above question is 1.

Step-by-step explanation:

Before proceeding to the explanation, let's have a quick revision of what a coefficient is!

• A coefficient is the constant that is commonly placed before a variable( i.e. x² in this case) and is multiplied by that variable.

Here, we are provided with the expression:

Here, we are provided with the expression:2 + x² + x

We are supposed to find the coefficient of x².

We can easily find out that there's a hidden number 1 present before each of the variables.

Hence, expression can be written as -

Hence, expression can be written as -2 + 1x² + 1x

Now, coefficient of x² = 1

Answer 2

The equation 2+x²+x can be written as 2+(1)x²+x

We know that, coefficient is the number which multiplies the variable.

Here, the number that multiplies the variable x² is 1

, the coefficients of x² in 2+x²+x is 1.
