Step-by-step explanation:

Let's simplify step-by-step.

Let's simplify step-by-step.(a2−b2)(3)+(b2−c2)(3)+(c2+a2)(3)

Let's simplify step-by-step.(a2−b2)(3)+(b2−c2)(3)+(c2+a2)(3)Distribute:

Let's simplify step-by-step.(a2−b2)(3)+(b2−c2)(3)+(c2+a2)(3)Distribute:=(a2)(3)+(−b2)(3)+(b2)(3)+(−c2)(3)+(c2)(3)+(a2)(3)

Let's simplify step-by-step.(a2−b2)(3)+(b2−c2)(3)+(c2+a2)(3)Distribute:=(a2)(3)+(−b2)(3)+(b2)(3)+(−c2)(3)+(c2)(3)+(a2)(3)=3a2+−3b2+3b2+−3c2+3c2+3a2

Let's simplify step-by-step.(a2−b2)(3)+(b2−c2)(3)+(c2+a2)(3)Distribute:=(a2)(3)+(−b2)(3)+(b2)(3)+(−c2)(3)+(c2)(3)+(a2)(3)=3a2+−3b2+3b2+−3c2+3c2+3a2Combine Like Terms:

Let's simplify step-by-step.(a2−b2)(3)+(b2−c2)(3)+(c2+a2)(3)Distribute:=(a2)(3)+(−b2)(3)+(b2)(3)+(−c2)(3)+(c2)(3)+(a2)(3)=3a2+−3b2+3b2+−3c2+3c2+3a2Combine Like Terms:=3a2+−3b2+3b2+−3c2+3c2+3a2

Let's simplify step-by-step.(a2−b2)(3)+(b2−c2)(3)+(c2+a2)(3)Distribute:=(a2)(3)+(−b2)(3)+(b2)(3)+(−c2)(3)+(c2)(3)+(a2)(3)=3a2+−3b2+3b2+−3c2+3c2+3a2Combine Like Terms:=3a2+−3b2+3b2+−3c2+3c2+3a2=(3a2+3a2)+(−3b2+3b2)+(−3c2+3c2)

Let's simplify step-by-step.(a2−b2)(3)+(b2−c2)(3)+(c2+a2)(3)Distribute:=(a2)(3)+(−b2)(3)+(b2)(3)+(−c2)(3)+(c2)(3)+(a2)(3)=3a2+−3b2+3b2+−3c2+3c2+3a2Combine Like Terms:=3a2+−3b2+3b2+−3c2+3c2+3a2=(3a2+3a2)+(−3b2+3b2)+(−3c2+3c2)=6a2
