Factorise : 4a^2 - 12ab + 9b^2 + 4a - 6b

4a 2 \- 12ab \+ 9b 2 \+ 4a \- 6b Using the formula [∵ (x \- y) 2 = x 2 \+ y 2 \- 2xy] = (4a 2 \- 12ab \+ 9b 2 ) \+ 4a \- 6b = ((2a) 2 \- 2 2a 3b \+ (3b) 2 ) \+ 4a \- 6b = (2a \- 3b) 2 \+ (4a \- 6b) Using the formula [∵ (x 2 \- y 2 ) = (x \+ y)(x \- y)] = (2a \- 3b) 2 \+ 2(2a \- 3b) = (2a \- 3b)((2a \- 3b) \+ 2) = (2a \- 3b)(2a \- 3b \+ 2) Hence,4a 2 \- 12ab \+ 9b 2 \+ 4a \- 6b = = (2a \- 3b)(2a \- 3b \+ 2)
