( a2 ) ( a2+1 )
-18
(a+b+c) (a+b-c)
a2 + -5a2 - a2 - a = a2 - 5a2 - a2 - a = a2 - 6a2 - a = -5a2 - a
a2 + a2 = 2a2
That factors to (x + 5)(x + 4)
( a2 ) ( a2+1 )
a2 - 4a + 4
-18
If that's 9a2, the answer is a(a2 - 9a + 3) x(5x2 + 3x - 1) -8d(d2 + 3d + 1)
-18
(a2+2b2-2ab)(a2+2b2+2ab)
It is: (a+1)(a+3) when factored
(a + 9)(a - 3)
a2 + 12a + 27 = (a + 3)(a + 9)
7a = -12
(a+b+c) (a+b-c)
