This week we learned how to multiply rational expressions in fraction form. For this question you want to factor as much as possible. Once the equations is factored as much as possible, cross out like terms.

This week we learned how to simplify rational fractions. These are basically fractions that will involve factoring. A way to make these questions simpler is by crossing out common factors in the denominator and numerator of the fraction because if you divide them they’re just going to equal 1 anyways. We also learned that it is important to know the non-permissible values of x in the denominator. It is important to know because our denominator can never equal 0. therefore the non-permissible values of this expression are -5, -8, and 0.

on This week in math he learned how to graph reciprocal quadratic functions. When beginning these questions it is always easiest to start by graphing the original equation, in this example it is x squared minus 3. After graphing this draw a broken vertical line on the zeros or x-intercepts, because this graph has 2 solutions it will have 3 hyperbolas. The 2 “L” shaped hyperbolas hover right above the x-axis and almost touching the broken lines. The hyperbola on the bottom follows the same rules except it’s on the other side of the broken line.

This week in precalc we learned how to solve 2 inequalities by combining the equations. this only works when the equations have 2 variables. An important part of this process is when you send one equation to the other side of the equal sign, that they’re being added or subtracted properly or else the whole process will be ruined as the zeros will not be equal.
