This week in Precalc 11 we worked on solving rational expressions by multiplying and dividing and we also learned how to write the non-permissible values. We first started off by simplifying radical expressions. When you are given an expression the first thing that you want to do is look if you can factor anything on […]
Grade 11
Week 11 – Precalc 11
This week in Precalc 11 we learned how to solve an inequality algebraically with parabolas. When you are given a graph that already has a parabola on it or you are given an equation, you are able to solve it using inequalities. If you are given a parabola that is opening up with the answer […]
Week 10 – Precalc 11
This week in Precalc 11 we continued to work on graphing quadratic equations and changing them into their different forms. We also learned how to find the equation of a graph when we were only given the vertex and another coordinate. The first step it to figure out what formula you are going to use […]
Week 9 – Precalc 11
In Precalc 11 this week, we continued to work on Quadratic equations and graphing them. We learned about the difference between general and standard form of the equation and how to graph equations and how to write an equation for the graph. General form is when the equation is in y=ax^2+bx+c and y=a(x-m)^2+n is standard […]
Week 8 – Precalc 11
This week in Precalc 11 we had another unit test and it was on solving quadratic equations. During the week we did a lot of review on the three different ways to solve them before we did out test which was on Wednesday. After we finished the test we spent the rest of the week […]
Week 7 – Precalc 11
In Precalc 11 this week, we learned how to solve using the quadratic formula. Solving using the quadratic formula is one of the three ways to solve an equations, but this method will always get the right answer when solving. The only difficult part of using the quadratic formula is remembering what it is. Once […]
Week 6 – Precalc 11
This week in Precalc 11 we learned more about solving quadratic equation with factoring. We used our previous knowledge from the unit before on factoring and used it to hep us with solving quadratic equations. To be able to tell whether an equation is linear or quadratic is with the degree or exponent. You can […]
Week 5 – Precalc 11
This week in Precalc 11 we had our second unit test on radical operations. We spent a lot of the time during the week reviewing for the test and doing lots of practice, but we were able to start talking and doing some work on our third unit which is solving quadratic equations. Most of […]
Week 4 – Precalc 11
I learned how to rationalize a monomial and binomial fraction in Precalc 11 this week. When dealing with fractions the denominator has to be a positive number, not a square root, so we learned how to take away the square root in the denominator. Here are two step-by-step examples of rationalizing the denominator for a […]
Week 3 – Precalc 11
In Week 3 of Precalc 11 we had our first unit test and then we switched to unit 2, roots and radicals. We just started this unit and and I have already learned a few different concepts, one of them being adding and subtraction roots. The first thing to know when you are looking to […]
