how do you solve this equation?

Question

(4x+2y)^2=

Answer 1

If you really meant EXPAND (4x + 2y)², then either multiply

 

(4x + 2y)(4x + 2y) = ?

 

or apply the familiar formula for the square of a binomial:

 

(a + b)² = a² + 2ab + b², 

 

where

 

a = 4x

b = 2y.

Answer 2

to be an equation, there must be a value or expression on each side of the = symbol.

 

In this case there could be solution due to the omission of the RHS as well as the fact that there are two variables, x & y, so that one could only solve for y in terms of x, or vice versa.
