... the form ax2 + bx + c where a=1, look for the integers r and s such that r*s=c and r+s=b. Then factor the expression. x2+bx+c=(x+r)(x+s) Factoring the Difference of Two Squares: a2-b2=(a+b)(a-b). Factoring Perfect-Square Trinomials: a2+2ab+b2=(a+b)2 a2-2ab+b2=(a-b)2 You can sometimes use factoring to solve an equation and to find zeros of a function. A zero function f is any number r such that f(r)=0 Zero-Product ... ...
