Question

a² + b² = ?
answer quickly​

Answer 1

Answer:

The difference of two squares is subtracting a square number from another squared number. And these numbers don’t have be perfect squares. Thankfully, difference of squares can be factored easily.

a² - b² is ubiquitous in mathematics and it is also supercalifragilisticexpialidocious for algebra.

If we speak algebraically:

(a + b) (a - b) = a² + ba - ab -b²

= a² - b²

Step-by-step explanation:

Answer 2

A^2+B^2 =(A+B)^2 -2AB


Proof
= A^2 + B^2=(A^2+B^2+2AB)-2AB
= A^2 + B^2 =A^2+B^2+2AB -2AB
= A^2 + B^2
