### Solving Quadratic Equations With Factoring

Solving Quadratic Equations by Factoring is Chapter 13.7 page 955 1) Quadratic Equation is in STANDARD FORM (ax^2 + bx + c = 0 where a is positive) Factor trinomial: x^2 + bx +c =(X + m)( X +n)=0 ,which :(mn=C),and (m+n=b) (X + m)=0 ---->X = - m , and (X + n)=0----> X= - n 2) Pythagorean Theorem in Right triangle (
