Factor this expression completely, then place the factors in the proper location on the grid. 5x3 + 40y6

For this case we have the following expression:
 5x3 + 40y6
 Common factor 5:
 5 (x3 + 8y6)
 Factoring the expression within the parenthesis we have:
 5 ((x + 2y2) (x2 - 2xy2 + 4y4))
 Answer:
 The factored expression is given by:
 5 ((x + 2y2) (x2 - 2xy2 + 4y4))
