Oh my goodness . . .

What do you get when you multiply a number by itself ?
Do you get the square of the number ?

And what do you get when you square the square root of a number ?
Is it the number inside the square root ?

For just a second, let's take the quantity (4t - 3) and call it ' Q '.
Then the problem is to multiply
                                                   √Q times √Q .
Isn't that just ' Q ' ?

And is this enough help ?
