An identity is an equation that is satisfied by all numbers from its replacement set. Example 1 Consider the equation 2x-1 = x+2. The replacement set here is the set of all real numbers. The equation is conditional since, for example, 1 is a member of the replacement set but not of the solution set. Example 2 Consider the equation (x-1) (x+1 ... Notice that in order to apply the quadratic formula, we must transform the quadratic equation into the standard form, that is, [latex]a{x^2} + bx + c = 0[/latex] where [latex]a e 0[/latex].
