$y= (6x+11)(6x+11)$

There are many factor combinations, but it is significant that both 36 and 121 are perfect squares. Try those factors first.6

Write down factors and find the cross-product.

$"6 11" rArr 6xx11 = 66$
$"6 11" rArr 6xx11 = 66" "66+66 = 132$

The signs are the same (because of +121)
They are both plus (because of +132)

$y= (6x+11)(6x+11)$
