The Bakhshali Manuscript dated to have been written in India in the 7th century CE contained an algebraic formula for solving quadratic equations, as well as quadratic indeterminate equations (originally of type ax/c = y). Mohammad bin Musa Al-kwarismi (Persia, 9th century) developed a set of formulae that worked for positive solutions. Abraham bar Hiyya Ha-Nasi (also known by the Latin name Savasorda) introduced the complete solution to Europe in his book Liber embadorum in the 12th century. Bhāskara II (1114–1185), an Indian mathematician–astronomer, gave the first general solution to the quadratic equation with two roots.The writing of the Chinese mathematician Yang Hui (1238-1298 AD) represents the first in which quadratic equations with negative coefficients of 'x' appear, although he attributes this to the earlier Liu Yi.
Need help with algebra? You are not alone! Algebra is one of the
most difficult subjects for many students, even those who are normally
high achievers. But here's some good news: once a student becomes
familiar with the special "language" of algebra, it can become one of
the easiest, and even most enjoyable, things for them to do!
Algebra is based on a special kind of logic--once it clicks in
students' heads, it becomes easy to apply to any type of problem. The
trouble is, some students learn best at different paces, and in
different environments, than others. For many, a 45-minute classroom
session, surrounded by the distractions of their peers, is simply not
the ideal way to learn.
Even if students pay close attention in class, they are liable to
miss a lesson or a portion of a lesson for any number of reasons. And
since math works like a chain, with one concept leading to the next, a
"missed link" causes subsequent material to stop making sense. With
Math Made Easy's innovative program of DVDs, students no longer feel
embarrassed when they need to have a concept repeated to them. They
simply rewind the disc to hear the information explained again!
Our sister site, TutorialChannel.com, is the perfect companion to
our DVDs, allowing users to download free practice tests, chart their
progress, receive live help from online tutors, and watch streaming
videos of algebra lessons. Our system guides students step-by-step
through each concept, targeting weak areas while building overall
comprehension. With all these tools at their disposal, even students
currently receiving very poor or failing grades in algebra can earn As
and Bs. Call 1-888-MATH-HELP, and receive your free consultation today!
