Answer 1

Use the quadratic formula\[x = \frac{ -b \pm \sqrt{b^{2} - 4ac} }{ 2a }\]

Answer 2

If the factors aren't obvious, do as @Soumyadeep suggested and use the quadratic formula. Knowing that your equation is in the form of \(ax^2+bx+c=0\) you can first solve the discriminant, \(b^2-4ac\), to see if you get a perfect square. If you do get a perfect square, the equation can be factored and you must then solve for your roots. Once you have reached the point of \(x=\frac{d}{e}\) and \(x=\frac{f}{g}\) you can work backwards to get your factors:\[ex-d=0~and~gx-f=0\]

Answer 3

@eSpeX best explaination!
