Two complex solutions are found and are checked in the original equation to verify that they are solutions.There is one "special" factoring type that can actually be done using the usual methods for factoring, but, for whatever reason, many texts and instructors make a big deal of treating this case separately. Remember that "trinomial" means "three-term polynomial". For instance:.
Recognizing the pattern to perfect squares isn't a make-or-break issue — these are quadratics that you can factor in the usual way — but noticing the pattern can be a time-saver occasionally, which can be helpful on timed tests. The trick to seeing this pattern is really quite simple: If the first and third terms are squares, figure out what they're squares of. Multiply those things, multiply that product by 2and then compare your result with the original quadratic's middle term.
If you've got a match ignoring the signthen you've got a perfect-square trinomial. And the original binomial that they'd squared was the sum or difference of the square roots of the first and third terms, together with the sign that was on the middle term of the trinomial.
Well, the first term, x 2is the square of x. The third term, 25is the square of 5. Multiplying these two, I get 5 x. Multiplying this expression by 2I get 10 x. This is what I'm needing to match, in order for the quadratic to fit the pattern of a perfect-square trinomial. Looking at the original quadratic they gave me, I see that the middle term is 10 xwhich is what I needed.
So this is indeed a perfect-square trinomial:. I know that the first term in the original binomial will be the first square root I found, which was x. The second term will be the second square root I found, which was 5.Square root in 3 seconds - math trick
Looking back at the original quadratic, I see that the sign on the middle term was a "plus". This means that I'll have a "plus" sign between the x and the 5. Then this quadratic is:. The first term, 16 x 2is the square of 4 xand the last term, 36is the square of 6. Actually, since the middle term has a "minus" sign, the 36 will need to be the square of —6 if the pattern is going to work.
Just to be sure, I'll make sure that the middle term matches the pattern:. It's a match to the original quadratic they gave me, so that quadratic fits the pattern of being a perfect square:.
Factoring Perfect Square Trinomials
I'll plug the 4 x and the —6 into the pattern to get the original squared-binomial form:. The first term, 4 x 2is the square of 2 xand the last term, 36is the square of 6 or, in this case, —6if this is a perfect square. However, looking back at the original quadratic, it had a middle term of —25 xand this does not match what the pattern requires. If I use the regular methods for factoring quadratic-type polynomialsI can factor this just fine. But what if this is in the homework for the section in my textbook on perfect-square binomials?
Naturally, I'm going to be thinking that the author is expecting me to notice a perfect square.
The first term is x 4whose square root is x 2. The third term is 1whose square root is just 1. Does the middle term, 2 x 2fit the pattern for perfect-square binomials? I'll check:. It's a match to the original polynomial, so this is a perfect-square trinomial. With the "minus" on the middle term of what they gave me, the original squared-binomial form looks like:. The instructions say to "factor fully".
That's often a clue that there may be some more factoring that I could, after the usual bit is completed. Can I factor any more here? Yes, I can.Skip to main content. Factoring Polynomials.
