Algebra I Glossary

a U-shaped graph which is produced by a quadratic equation

lines that have the same slope and different y-intercepts

a method of multiplication in which each factor is split into a sum of its parts. Every part of one factor is multiplied by every part of the other factor, then these partial products are added together. For example, (5)(23) = (5)(20 + 3) = 5(20) + 5(3) = 100 + 15 = 115

any of the squares of the integers. Since 12 = 1, 22 = 4, 32 = 9, etc., 1, 4, and 9 are perfect squares

a trinomial that is the product of a binomial times itself, such as r2 + 2rs + s2 (from (r + s)2), and r2 – 2rs + s2 (from (r – s)2)

groupings in which the order of members matters

lines that have opposite reciprocal slopes

a form of linear equation, written as (FIX) , where m is the slope and (x1, y1) are the co-ordinates of a point

a monomial or sum of monomials, like 4x2 + 3x – 10

a monomial or sum of monomials, like y = 4x2 + 3x – 10
