Decending powers of x

I was in one of my colleagues lessons this week.and he was teaching the class to expand quadratic brackets. As the lesson went on he noticed that a number of pupils had been writing the X squared term, then the constant term then the X term so he pulled the class together to tell them that conventionally we write quadratic equations in decending powers of x. 156 more words

QUADRATIC EQUATIONS FROM INDICES

Solving for x in an equation where the unknown variable is in indices can be a bit tricky. They may be solved by equalizing the base on both sides of the equation and then deriving quadratic equation out of the indices. 11 more words
