a2x+5a2x2-2ax

You have not written an equation, so there is nothing to "solve". All you can do is try to simplify or factor what you have written.

Factor out the ax. Use ^ for exponents.

a^2x + 5a^2x^2 - 2ax = ax(a + 5ax -2)

To simplify the given expression, let's combine like terms:

a^2x + 5a^2x^2 - 2ax

First, we notice that there are three terms in the expression: a^2x, 5a^2x^2, and -2ax.

Next, we check for like terms that can be combined. Like terms have the same variables, raised to the same powers.

In this expression, we have three variables: a, x, and x^2.

Looking at the coefficients (numbers in front of the variables), we can see that 1, 5, and -2 are different, so the only way to combine the terms is by verifying if the variables and their powers are the same.

The variables, a and x, are the same in all three terms, so we can combine them.

Combining like terms:

a^2x + 5a^2x^2 - 2ax

Now, let's combine the terms with the same variables. Here's how:

First, let's find the common factors in the expression, which is a.

Taking out a as a common factor:

a(ax + 5ax^2 - 2x)

When we factor out a, we are left with the expression inside the parentheses:

ax + 5ax^2 - 2x

Hence, the simplified form of the given expression is a times (ax + 5ax^2 - 2x).
