What two terms give you the first when multiplied and what two terms give you the second? If you forget or don't see that it is the difference of squares you can still figure it out by reasoning it out. How do we factor the difference of squares? It is: (square root of first term + square root of second term)(square root of first term - square term of second). We are dealing with the difference (notice the subtraction sign between the terms) of squares. You might notice that is a perfect square. Next we look at the last term (1) and think what can you multiply by itself to get 1? That's 1 as (1)(1)=1.

If you remember how to distribute twice (teachers usually use the term F.O.I.L.) this question is asking you to go backwards.the expression is what you get when you "FOIL" so what were the two terms before?Ģ5x^2 -> What can you multiply to get 25x^2? Since the terms have to be identical that's 5x. I will do PART A using "^" and PART B using an editor that will make the notation look as it does in your notebook so you see both ways.Īs the expression given is the area of a square (and in a square the sides are all of equal length) when we factor (write as a product) this expression we should get two identical factors. We can also use a program like equation editor (part of Word) so that the expressions look like they would if you wrote then by hand in your notebook.

My guess is that by (25x2-10x+1) you mean "25 x squared plus 10x plus 1." Usually to show the exponent (x squared) we use the ^ symbol so that means for Part A you are being asked to factor 25x^2 -10x + 1. Before getting started, let's look at notation.
