Factorize expressions: 4x2 + 12xy + 9y2
We have,
4x2 + 12xy + 9y2
By using the formula (x + y)2 = x2 + y2 + 2xy
(2x)2 + (3y)2 + 2 (2x) (3y)
(2x + 3y)2
(2x + 3y) (2x + 3y)
Divide as directed (x4 – 81) ÷ (x3 + 3x2 + 9x + 27)
Divide as directed (3x3 – 6x2 – 24x) ÷ (x – 4) (x + 2)
Divide as directed 15(y + 3)(y2 – 16) ÷ 5(y2 – y – 12)
Factorise x2 + 2xy – 99y2
Factorise 6x2 – 5xy – 6y2
