Question

Combine the like terms to simplify the expression. 4a2 + 7b2 + 5b2 – 2a

4a2 + 12b4 – 2a

4a2 + 12b2 – 2a

2a + 12b2

2a + 12b4

Answer 1

For this case we must simplify the following expression:

`4a ^ 2 + 7b ^ 2 + 5b ^ 2-2a`

We add similar terms taking into account that:

Equal signs are added and the same sign is placed.

`4a ^ 2 + (7b ^ 2 + 5b ^ 2) -2a =\\4a ^ 2 + 12b ^ 2-2a`

Thus, the correct option is option B.

Answer:

Option B
