Question

How do you find the product of `(6a-3)(7a-4)`?

Answer 1

`42a^2-45a+12`

Explanation:

Each term in the second bracket must be multiplied by each term in the first bracket. This is shown below.

`(color(red)(6a-3))(7a-4)`

`=color(red)(6a)(7a-4)color(red)(-3)(7a-4)`

distributing gives.

`=42a^2-24a-21a+12`

collecting like terms.

`=42a^2-45a+12`
