Factorize expressions: a2 + 4ab + 3b2
We have,
a2 + 4ab + 3b2
By using factors for 3 i.e., 3 and 1
a2 + ab + 3ab + 3b2
By grouping we get,
a (a + b) + 3b (a + b)
(a + 3b) (a + b)
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
