Question

`(6x+27) (12x-9)`

Answer 1

72x^2+270x-243 I just did the same problem

Answer 2

For this case we must apply distributive property term by term, to simplify the expression:

`(6x) (12x) + (6x) (- 9) + (27) (12x) + (27) (- 9) =`

We have to:

`+ * - = -`

So:

`72x ^ 2-54x + 324x-243`

Different signs are subtracted and the sign of the major is placed:

`72x ^ 2 + 270x-243`

ANswer:

`72x ^ 2 + 270x-243`
