Question

factorise
a⁴-11a²+10.

$factorisation of \: trinomial \: expression$

​

Answer 1

Answer:

=a⁴-11a²+10

=a⁴-10a²-a²+10 [ middle term factorisation ]

= a²(a²-10) -1(a²-10)

= (a²-10) (a²-1)

Answer 2

Answer:

a4 - 10a2 - 1a2 + 10

a^2(a^2 - 10) - 1(a^2 - 10)

(a^2 - 10)(a^2 - 1) = 0

this implies that

a=√10 or a = 1
