In summary, the simplified form of (x+a)^2 * (x-a)^2 is x^4 - 2ax^2 + a^2. This can be achieved by using the FOIL method to expand the expression or by multiplying the equivalent expression (x^2 + 2ax + a^2) * (x^2 - 2ax + a^2). The simplified form is important for quick calculations and better understanding of the original expression.

Which is the fastest way to simplify:
[tex](x+a)^2*(x-a)^2[/tex] to [tex](x^2-a^2)^2[/tex] ?
thx

Think of [tex](x+a)^2*(x-a)^2[/tex] as [tex](x+a)*(x-a)*(x+a)*(x-a)[/tex] and [tex](x^2-a^2)[/tex] as [tex](x-a)*(x+a)[/tex]

There's the fastest way
[tex] A^{2}\cdot B^{2}=(AB)^{2} [/tex]

Apply it for your case.

FAQ: How Can You Quickly Simplify (x+a)^2 * (x-a)^2 to (x^2-a^2)^2?

What is the simplified form of (x+a)^2 * (x-a)^2?

The simplified form of (x+a)^2 * (x-a)^2 is x^4 - 2ax^2 + a^2.

How do I simplify (x+a)^2 * (x-a)^2?

To simplify (x+a)^2 * (x-a)^2, you can use the FOIL method, which stands for First, Outer, Inner, Last. This means you multiply the first terms, then the outer terms, then the inner terms, and finally the last terms. Then you combine like terms and you will get the simplified form.

Can I expand (x+a)^2 * (x-a)^2 to get the simplified form?

Yes, you can expand (x+a)^2 * (x-a)^2 to get the simplified form. This will result in x^4 - 2ax^2 + a^2, which is the same as the simplified form.

Is (x+a)^2 * (x-a)^2 the same as (x^2 + 2ax + a^2) * (x^2 - 2ax + a^2)?

Yes, (x+a)^2 * (x-a)^2 and (x^2 + 2ax + a^2) * (x^2 - 2ax + a^2) are equivalent expressions. They both simplify to x^4 - 2ax^2 + a^2.

Why is the simplified form of (x+a)^2 * (x-a)^2 important?

The simplified form of (x+a)^2 * (x-a)^2 is important because it allows us to quickly and easily perform calculations involving this expression. It also helps us to better understand the relationship between the original expression and its simplified form.
