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.
This week we learned how to solve for quadratic inequalities. When solving for these equations, factoring will be a key point as it gives the zero values. I like using the number line as a visual to find whether or not test numbers would give negative or positive results. Although this method is somewhat time consuming, it shows a simple, step by step way of solving.
