In mathematics, you don't understand things. You just get used to them.
Some cause happiness wherever they go; others, whenever they go.
If you can not overcome with talent...overcome with effort.
So ?1 times ?2 must come to 6t^2
and ?3 times ?4 must come to 12.
There are several ways of achieving this, but find one where the two 't' terms come to -18t together.
ps. In this example, it is also possible to factorise a 6 before you start on the quadratic. This will make it easier to find the ?s.
And a factorisation is not complete until the numbers are factorised out too.
