Factorise the following: a 4 - 11a 2 + 10

Factorising we get, a 4 - 11a 2 + 10 = a 4 - 10a 2 - a 2 + 10. = a 2 (a 2 - 10) - 1(a 2 - 10) = (a 2 - 10)(a 2 - 1) = (a 2 - 10)(a - 1)(a + 1) Hence, a 4 - 11a 2 + 10 = (a 2 - 10)(a - 1)(a + 1).

Answer

Factorising we get,

a⁴ - 11a² + 10 = a⁴ - 10a² - a² + 10.

= a²(a² - 10) - 1(a² - 10)

= (a² - 10)(a² - 1)

= (a² - 10)(a - 1)(a + 1)

Hence, a⁴ - 11a² + 10 = (a² - 10)(a - 1)(a + 1).
