Answer 1

Answer:

the answer is -1

Step-by-step explanation:

because there is no expression before it there is minus so the answer is -1

Answer 2

The coefficient of y³ in the expression y - y³ + y² is - 1

Given :

The expression y - y³ + y²

To find :

The coefficient of y³ in the expression

Concept :

Coefficients :

In a term of an algebraic expression the numerical factor of a term is called coefficients and any of the factors with the sign of the term is called coefficient of the product of the other factors

Solution :

Step 1 of 2 :

Write down the given expression

Here the given expression is y - y³ + y²

Step 2 of 2 :

Find the coefficient of y³ in the expression

We know that in a term of an algebraic expression the numerical factor of a term is called coefficients.

In the expression y - y³ + y² we see that

- y³ = ( - 1) × y³

Hence coefficient of y³ in the expression y - y³ + y² is - 1
