where is ab

coefficient of a is 4

Answer 2

Answer:

The coefficient of $a$ is $4$.

Step-by-step explanation:

We are given with the term $(2a-56)2$

We need to find the coefficient of $a$.

A coefficient is a multiplicative factor in some term of a polynomial or an expression.

It is generally a number.

We need to expand the given equation.

Expanding, we get

$(2a-56)2=4a-112$

Since the term is $4a-112$, the coefficient of $a$ is $4$.

The answer of $a$ is $4$.
