Hi guys,

I'am just doing quadratic equations. One of the possible solution to execute quadratic equations is to factor out their terms.

Do you have any hints how to do that?

I know that sum should be equal to b and product equal to c but sometimes it takes me quite long to come up with a solution.

Let me try to make it easy: -
In the equation ax^2+bx+c = 0, you have to factorize 'c' in such a way that the sum of factors must be equal to 'b' and product, ofcourse, equal to 'c'.
