When watching the video the viewer should pay attention to how i multiplied the first equation by negative one so that it is switched however when using rref form i have to use the original problem. Also how to find the first zero i may use either the first or second row but to find the second zero i must use row 1 and to find the last zero i must use row 2 to help me. Also to find the stairstep ones i multiply by the inverse of the leading coefficient. We use rref form on our calculator to check if our answers are right. Dont forget to use the ORIGINAL equation and if there is no variable we put a zero. Our answer that is there should match up with what we got.
