Factorise : a^2 - 16b^2 - 2a - 8b

a 2 \- 16b 2 \- 2a \- 8b Using the formula [∵ (x 2 \- y 2 ) = (x \+ y)(x \- y)] = (a 2 \- 16b 2 ) \- (2a \+ 8b) = (a \- 4b)(a \+ 4b) \- 2(a \+ 4b) = (a \+ 4b)((a \- 4b) \- 2) = (a \+ 4b)(a \- 4b \- 2) Hence,a 2 \- 16b 2 \- 2a \- 8b = (a \+ 4b)(a \- 4b \- 2)

Answer

a² - 16b² - 2a - 8b

Using the formula

[∵ (x² - y²) = (x + y)(x - y)]

= (a² - 16b²) - (2a + 8b)

= (a - 4b)(a + 4b) - 2(a + 4b)

= (a + 4b)((a - 4b) - 2)

= (a + 4b)(a - 4b - 2)

Hence,a² - 16b² - 2a - 8b = (a + 4b)(a - 4b - 2)
