Try to factor the equation
Consider two factors that give the final term (9*5, 15*3, 45*1). Do the same with the first term (2*2, 4*1). Is there any combination of the two that will add to 30?
All I can get for the middle term are -27, - 29, -63 or -41. Do you have a typo in your equation?
What are the solutions of the quadratic equation below?
