Thoughtfully split the expression at hand into groups, each group having two terms :
Group 1: -9x-9y
Group 2: 2x3+4x2y
Group 3: 2xy2-5
Pull out from each group separately :
Group 1: (x+y) • (-9)
Group 2: (x+2y) • (2x2)
Group 3: (2xy2-5) • (1)
Looking for common sub-expressions :
Group 1: (x+y) • (-9)
Group 3: (2xy2-5) • (1)
Group 2: (x+2y) • (2x2)
