Answer:
ans is 2a
Explanation:
a[2a-3(1-a)] + 5(a-a^2)
=a{2a-3+3a] + 5a - 5a^2
=a[5a-3] + 5a - 5a^2
=5a^2 - 3a + 5a - 5a^2
=2a
a(2a-3(1-a))+5(a-a^2)
distribute the inner most parenthesis
a( 2a -3+3a))+5(a-a^2)
combine like terms
a(5a-3) +5(a-a^2)
distribute both sets of parenthesis
5a^2 -3a +5a-5a^2
5a^2-5a^2 -3a+5a
2a
