Question

Write $a^2-b^2$ formula.

Answer 1

Write a formula for $a^2-b^2$:

The "difference of squares formula" is another name for the $a^2-b^2$ formula. Without actually computing the squares, the $a^2-b^2$ is utilized to calculate the difference between them.

$a^2-b^2=\left(a+b\right)\left(a-b\right)$

Hence, the formula for $a^2-b^2$ is $\left(a+b\right)\left(a-b\right)$.
