2 is.
a2 + -5a2 - a2 - a = a2 - 5a2 - a2 - a = a2 - 6a2 - a = -5a2 - a
depends what the value of 'a' is.
5a x a = 5a2
2a2+3a2 = 5a2
2 is.
8a(5a2-1)
(5a2 - 3)(5a2 + 3)
5a2-15 = 5 (a2-3) = 5 (a-sqrt(3))(a+sqrt(3)) as a2-b2=(a-b)(a+b)
a2 + -5a2 - a2 - a = a2 - 5a2 - a2 - a = a2 - 6a2 - a = -5a2 - a
5a(a+2b+b²)
depends what the value of 'a' is.
5A2 + 3 = 48 Therefore, 5A2 = 45 Therefore, A2 = 45/5 A = sqrt(9) A = 3
It is: 5a2
5a x a = 5a2
2a2+3a2 = 5a2
5a2 + 6ab=a(5a+6b)
