Question

Coefficient of y2

in expression 9y2 + 8 is __________​

Answer 1

Answer:

Coefficient of y2 = 9

Step-by-step explanation:

The coefficient of a variable is the number multiplied by that variable.

For example, in equation 2x + 3y +2 = 0.

Coefficient of x is 2

Coefficient of y is 3.

Let's take one more example,

In equation x² + 4x +7 = 0

Coefficient of x² = 1

Coefficient of x = 4

Similarly, in expression 9y2 + 8,

Coefficient of y2 = 9
