WebThe quadratic expression is called the standard form, the sum of a multiple of and a linear expression ( in this case). In general, standard form is We refer to as the coefficient of the squared term , as the coefficient of the linear term , and as the constant term. The function can also be defined by the equivalent expression . WebThe attention to structure continues in this lesson. Students relate the numbers in the factored form to the coefficients of the terms in standard form, looking for structure that can be used to go in reverse—from standard form to factored form (MP7). This lesson only looks at expressions of the form and where and are positive.
