(4v11-2v2) (6v11+8v2)

Question

Multiplication of binomials containing radicals.

Answer 1

The important thing to remember with radicals is that they are essentially to be treated like variables.  Let's multiply it out:

 

(24)(V11)² + 32(V11)(V2) - 12(V2)(V11) - 16(V2)²

 

The important thing to remember is that what is inside the square roots can be multiplied.  So:

 

(24)(11) + 32(V22) - 12(V22) - 16(2)

264 - 20(V22) - 32

262 - 20(V22)
