Question

a² – b² is equal to what ​

Answer 1

A^2-B^2=(A+B)*(A-B) is the answer

Answer 2

Given: The equation$a^{2} -b^{2}$.

We have to simplify the equation$a^{2} -b^{2}$.

We are solving in the following way:

As we know that from the standard formulas of mathematics$(a+b)(a-b)=a^{2}-b^{2}$.

Now we are simplifying the equation:

$=>(a+b)(a-b)\\=>a^{2}-ab+ba-b^{2} \\=>a^{2}-b^{2}$

We get,   $(a+b)(a-b)=a^{2}-b^{2}$

Hence, $a^{2}-b^{2} =(a+b)(a-b)$
