Answer by rapaljer(4671) (Show Source): You can put this solution on YOUR website!
The quadratic formula is
In this case, x^2 +12x+35=0, a=1, b=12, and c=35.
or
or
This problem can be checked by solving by FACTORING:
x^2 +12x+35=0
(x+5)(x+7)=0
x=-5 or x=-7
I have a LOT of resources on my own website on the topic of QUADRATIC FORMULA. To find my website, do a "BING" or a "GOOGLE" search for my last name "Rapalje". Near the top of the search list, you should see "Rapalje Homepage." Click on this, and look near the top of my homepage for the link "Basic, Intermediate and College Algebra: One Step at a Time." Choose "Intermediate Algebra", and look in "Chapter 4" for "Section 4.03, Quadratic Formula." This is my own explanation especially written for students who have trouble understanding math. I wrote this to students, NOT mathematicians, and I think you will find it easier to understand than your own traditional textbooks!! In addition to this page, the entire website is supported by my "MATH IN LIVING COLOR" pages, where the hardest problems are solved IN COLOR.
If you like my website, please recommend it to family and friends who have trouble understanding math!! It's ALL FREE!!!
