You may be familiar with solving the equation x^2=9. In Pre-Calculus 11, we extend our understanding of quadratics and lines by studying the meaning of the inequality symbol. factoring, quadratic formula, completing the square, graphing, square root method) Identifying characteristics of graphs (including domain and range, intercepts, vertex, symmetry), multiple forms, function notation, extrema.We can use our understanding of quadratics to determine the exact height of a basketball or find the optimal dimensions to maximize or minimize area. Quadratics is the largest math topic in Pre-Calculus 11. Difference of squares of the form a^2x^2-b^2y^2. By factoring, we reveal the roots of a polynomial which are also known as x-intercepts or solutions. This year we factor quadratics and next year we factor higher degree polynomials. We continue factoring this year in Pre-Calculus 11 because factoring is an important part of quadratic functions and equations.
