This week in math we learned about discriminants and how to determine the nature of a root. The discriminant equation is -4ac, as taken from the part of the quadratic

Week 6 in Precalc 11

This week in math we learned how to solve quadratic equations using the zero product law. A quadratic equation is one that has two answers. A linear equation has one

Week 5 in Precalc 11

This week in math we learned how to factor polynomial expressions, specifically ‘ugly’ ones using the ‘box method’. A helpful phrase to figure out if a polynomial expression is ugly

Week 4 in Precalc 11

This week in math we learned how to add and subtract like radicals. This means that if there are like radicals in an equation, you can simplify their coefficients. In

Week 3 – Precalc 11

This week in math we learned about absolute values. In simple terms, an absolute value is the distance a number is from 0. The official definition is: the absolute value

Week 2 – Precalc 11

This week in math we learned about geometric sequences. For the sequence to be geometric, each term must be multiplied by a constant, known as the common ratio, or ‘r’.
