We want to factor the following expression:
9x^8+6x^4(y+2)+(y+2)^29x
8
+6x
4
(y+2)+(y+2)
2
9, x, start superscript, 8, end superscript, plus, 6, x, start superscript, 4, end superscript, left parenthesis, y, plus, 2, right parenthesis, plus, left parenthesis, y, plus, 2, right parenthesis, squared
We can factor the expression as (U+V)^2(U+V)
2
left parenthesis, U, plus, V, right parenthesis, squared where UUU and VVV are either constant integers or single-variable expressions.
