Hace 2 días · Have you ever encountered an equation where an unknown variable, like x, is hiding under a square? If so, you’ve met a quadratic equation! These equations, though seemingly intimidating at first glance, can be solved using a powerful tool called the quadratic formula. This blog will be your guide to understanding and conquering quadratic equations with this formula.
Hace 5 días · In this explainer, we will learn how to form inequalities involving the lengths of the sides of a triangle given the measures of the angles of the triangle. In an isosceles triangle, we can recall that the angles opposite the sides of equal lengths are of equal measures.
Hace 4 días · We solve inequalities using some of the techniques used in solving equations. However, there are some important differences in the application of these techniques to inequalities.
Hace 4 días · The inequality x2 + 12x + 35 ≥ 0 has two critical points and three possible intervals for solutions. Choose each set of possible test points for the three intervals.
Hace 2 días · Write the inequality in interval notation. In interval notation, the inequality x ≥ − 4 is written as [ − 4, ∞). The square bracket [ − 4 indicates that − 4 is included in the interval, and the parenthesis ∞) indicates that the interval extends to positive infinity, which is not included.
