Big Ideas: Quadratic expressions have either no, one, or two real roots. Roots are the values that give the polynomial expression a value of zero. Factoring or using the quadratic formula allows us to find the roots. This lesson builds on students’ work with quadratic and linear functions. Students are asked to find the roots of linear and quadratic functions by factoring and using the quadratic formula. Vocabulary: roots, solutions, zeros
