You can put this solution on YOUR website! First write the equation in standard form:
Note that 12 can be factored as 12= (-1)*(-12), and the sum of the two factors is 13, which is equal to the coefficient of the middle term of the equation.
Thus the left side of the equation can be factored as
So x - 1 = 0 or x - 12 = 0
From x - 1 = 0 we have x = 1
From x - 12 = 0 we have x = 12
Thus the solutions to the equation are:
x = 1 or x = 12.
