Mariah started to find the solutions of x2 + 4x + 1 = 0. her work is shown below. x2 + 4x + 1 = 0 x2 + 4x = โ1 x2 + 4x + 4 = โ1 + 4 (x + 2)2 = 3 which describes the solutions of the equation? since โ2 and 3 are both rational, the sum and difference are rational. since โ2 and are both rational, the sum and difference are rational. since โ2 is rational and is irrational, the sum and difference are irrational. since is rational and is irrational, the sum and difference are irrational.
since โ2 is rational and is irrational, the sum and difference are irrational.
