There are two kinds of incomplete quadratic equations: 1) ax2+bx=0 (e.g. 4x2+2x=0)2) ax2+c=0 (e.g. 5x2-125=0)And the ways to solve them are as follows:Type 1) For example, 4x2+2x=0.You take out x...
There are many ways to solve a quadratic equation, but the quadratic formula works for all equations and is very quick. The formula is x= -b +/- the square root of (b^2 - 4ac)...
Factoring a quadratic equation is the opposite of expanding an equation. FOILing (first, outer, inner, last) is the common technique used to do this.
Example of foiling: (x + 4) (x + 1) = x2 + 1x +...
There is a new method, called Diagonal Sum Method, that quickly and directly give the 2 roots without having to factor the equation. The innovative concept of this method is finding 2 fractions...
