This week, we learned how to solve quadratic equations by factoring, completing the square, and using the quadratic formula. Factoring Factoring and using the zero product property is one of the easiest ways to solve a quadratic formula, and it works with rational roots. A quadratic equation is any equation that can be written in the…

This week in pre-calculus 11, we reviewed and extended our understanding of factoring polynomials. To remember the steps of factoring polynomials is simple. Just remember can divers pee easily underwater:) Common GCF (remainder) Difference of squares Pattern Easy (when the variable doesn’t have a coefficient) Ugly (if the variable has a coefficient) examples:
This week in precalculus we learned how to solve redical equations. There are rules to remember when multiplying and dividing radical expressions. Multiplication: 1) It is recommended to simplify first, because it is easier to simplify the smaller number 2) Remember to use the distributive property (FOIL aka the claw method) Division: 1) There should…
On the third week of precalculus, we began a new unit on absolute value. Absolute value is the principal square root of a number, and it is the distance of the number from zero. The absolute value of | -7 | and | 7 | are both 7. Example: -| 5-9×3 | *remember to use…

On the second week of precalculus 11, we learned about geometric sequences and series. In a geometric sequence, each term is multiplied by a constant, known as the common ratio(r). Geometric Sequences: 7,14,28,56,112.. = () = 7 () = 7(512) = 3584 Geometric Series: 4+12+36+108+324.. Sn= a( – 1) / r- 1 = 4 ( -1)…
-17, -11, -5, 1, 7… = + (n- 1)d = -17+ (50- 1)6 = -17+ (49)6 = -17+ 294 = 277 Sn= (2 + (n-1)d) Sn= (2(-17)+(50-1)6) Sn= 25(-34+(49)6) Sn= 25(-34+294) Sn= 25(260) Sn= 6500
I am a middle aged single white male named Biff Loman. I used to be a confident, popular highschool football player, who got all the pretty girls. My father has very high expectations for me. He expects me to fulfill all of his dreams as a salesman, and live the American dream in his perspective….

The literal poem is about a caged bird that sings, because its voice is the only thing left that it has due to all the restrictions. The caged bird cries to get someone’s attention and…
