A school designer wants to create a whiteboard with the optimal dimensions to enhance learning. It is determined that if one side of the whiteboard is x + 2y inches, the other side should be x^2 + 6xy - 5y^2 inches. Write an algebraic expression for the area of such a whiteboard, simplify, iclude correct units.

for optimal dimensions it shud be square:

so x + 2y= x^2 + 6xy - 5y^2

and area= (x + 2y)(x^2 + 6xy - 5y^2)

solving we get no solution .....
