Question

Simplify: 3a2 + 2(a + 2) – 3a(2a + 1).
​

Answer 1

3a²+2(9+2)-3a(2a+1)

3a²+2a+4-6a²-3a

3a²-6a²+2a-3a+4

-3a²-a+4

-3a²-(4-3)a+4

-3a²-4a-3a+4

-a(3a+4)+1(3a+4)

(3a+4)(1-a)

hope this helps

:)

Answer 2

Answer:

3a² + 2a + 4 - 6a² -3a

= 3a² -a +4

= sum = -1

-4/3a 3/3a (do not put 3a²)

product = 12

the final answer is (3a - 4) ( a + 1)
