Algebraic Identities Quiz for Class 8 Students

$a^2 - b^2$ = Difference of squares $a^3 + b^3$ = Sum of cubes $a^3 - b^3$ = Difference of cubes $a^2 + 2ab + b^2$ = Square of a binomial

Variable = A term that can take any value Coefficient = Number attached to the term of an algebraic expression Polynomial = Expression with one or more terms Identity = Equality true for all values of the variable
