Question 230138
Well it is possible to factor and solve this equation.  First we can divide both sides by 3 and we will get:<br>

0 = x^2+4x-45<br>

now we need to think of numbers that multiply to -45 and add to 5.  -5 and 9 work so the equation factors to:<br>

0 = (x-5)(x+9)<br>

and to solve the equation we use the zero product property and set each factor to 0 and you will get that x = 5 and x = -9.<br>
