Factorize expressions: 18a2x2 – 32
We have,
18a2x2 – 32
2 [(3ax)2 – (4)2]
By using the formula (a2 – b2) = (a-b) (a+b)
2 (3ax + 4) (3ax – 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
