How to Find Maxima and Minima of a Function?
Every function that curves up or down has maximum and minimum points — the peaks and valleys of its graph. Finding these points tells you the greatest or least output value a function can produce, whether over its entire domain (absolute extrema) or just in a local region (relative extrema). Algebra 1 focuses especially on […]
How to Solve a Quadratic Equation by Factoring?
Algebra 1 Solving a Quadratic Equation by Factoring Factoring a quadratic rewrites \(x^2 + bx + c\) as a product of two binomials, \((x + p)(x + q)\), by finding two numbers that multiply to \(c\) and add to \(b\). It’s the quickest route to a quadratic’s roots when the numbers cooperate. We’ll practice the […]
