Question

I need help on 25. I know the answer is 2a but I need to see the work. Please help I’ve tried so many possibilities.

Answer 1

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

combine like terms

5a^2-5a^2 -3a+5a

2a

Answer 2

Answer:

ans is 2a

Step-by-step 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
