Limit Algebraic Rules • Rule 1 – Plug the x xalue into the equation • If you get a/b and • b 0, the answer is a/b • b = 0 and a 0, the answer is d.n.e • you get 0/0 then go to higher rules
. • 0.0 • 0.1
Limit Algebraic Rules • Rule 2 – Factor and cancel return to Rule 1 • SOAP (a3 + b3) = (a + b)(a2 – ab + b2) • Diff of 2 squares (a2 - b2) = (a + b)(a – b) • a x2 + bx + c Find two numbers whose product is ac, but add to b
