Question

How do you multiply `(3p+5)(2p-4)`?

Answer 1

`6p^2-2p-20`

Explanation:

Start with the `3p`. Multiply this by `2p` and then by `-4` to get `6p^2 -12p`. Then do the same with the `-5`. This will get yo `10p-20`. Add these two equations together into `6p^2-12p+10p-20`, and simplify inti `6p^2-2p-20`.

If it helps you can think of it like a claw.
In the format (a+b)(c+d), draw lines from a to c and d, and then from b to c and d underneath. The end result looks a bit like a crab claw and is an easy way to remember how to go about attempting these questions.
Use steps, and add them together into a final equation to make sure you don't get confused. Don't worry about doing too much working out! It's impossible to have such a thing.
