Factorize expressions: a2 + 2ab + b2 – 16
We have,
a2 + 2ab + b2 – 16
By using the formula (a – b)2 = a2 + b2 – 2ab
(a + b)2 – 42
By using the formula (a2 – b2) = (a+b) (a-b)
(a + b + 4) (a + b – 4)
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
