Question

What is the coefficient of the x2-term of the algebraic expression 2x^4 + x^2 - x+7

Answer 1

+1 is coefficient of x².

Explanation:

We have given an expression.

2x⁴+x²-x+7

We have to find the coefficient of x².

Definition of coefficient:

Coefficient is defined as the which is used to multiply a variable.

From given expression, we have

(+2)x⁴+(+1)x²+(-1)x+(7)

Hence , we notice from above expression

The number which is used to multiply with x² is +1.

Hence , the coefficient of x² in given expression is +1.

Answer 2

The coefficient of the x2-term of the given algebraic expression is: 1.

Explanation:

The coefficient of the x2-term of the algebraic expression 2x^4 + x^2 - x+7 is the number that multiplies x^2. When we don't see a number it is supposed to be 1, in this case positive (because of the "+" sign)
