This week in pre-calc we learned how to factor using trinomials.
There are a couple steps to figuring this out, but once you have figured it out it is very simple.
- identify a,b, and c in the trinomial ax2+bx+c.
- write down all factor pairs of c.
- identify which factor pair from the previous step sums up to b.
- Substitute factor pairs into two binomials.

This week in Ms burtons pre calc class we learnt how do solve using the quadratic equation.
To solve this it’s easiest to determine was terms are A,B, and C. Once these variables are determined substitute these variables for the numbers from the equation. Use bedmas to solve for X
This week we learned how to multiply radicals. Multiplying radicals is very easy. JUST DO IT.
This week in precalc I learned that when doing absolute values if a negative number is within braces it really means its a positive absolute value. We know this because it all depends on the numbers distance from 0.
