Question

a² + b² plz explain me ​

Answer 1

a² + b²=c² Subtract 2ab from both sides. The last equation, a² + b²=c², is called the Pythagorean Theorem. We say “The sum of the squares of the legs of a right triangle equals the square of its hypotenuse.” The legs of the hypotenuse are on the other side.

Answer 2

Answer:

(a+b)^2-2ab

Step-by-step explanation:

we know that (a+b)^2=a^2+b^2+2ab

if 2ab comes to right side

a^2+b^2=(a+b)^2-2ab
