During this week in Precalc Functions, my class and i had a quiz on graphing and factoring Polynomials.It was 6 questions that i thought i could master, but come to find out i needed alot more practice with factoring the functions.
As i got to the botton two on factoring, i starred at the last one for almost 2 minutes straight. Now i knew the quiz was open note, but if i looked at my notes that means i dont know that part of the material and means i wont still know it when the test comes around. So i looked at my Survival Guide: Factoring pink sheet. This eqaution i was solving was x^4 - 16. When i solved my equation i got (x^2-4)(x^2+4) and i left it like that. Well, i wasnt done yet! it can still be factored more because 4 is a perfect square root.
Overall, i knew on the quiz that the last 2 questions on factoring i got wrong because i never completly finished factoring them. So before the test tuesday i am studying studying studying and tommorow i will be asking my group and Mr Jackson help on factoring. i need to learn how to solve equations with out my notes and i also need to learn to finish square rooting if there is some and finish cube rooting if it is a perfect number for it.
