Two ways: 1) guess factors(trial and error) 2) use quadratic formula. If you use this method then a = -3, b = -6 and c = -1
x = -b +/- [sqrt(b^2 -4ac)/2a] substituting a, b, and c into our equation we get: x = - (-6)+/- [sqrt ((-6)^2) - 4(-3)(-1))/2 (-3)] x = + 6 +/- [sqrt (36 -4 (3)/-6)] if I didnt make a mistake in my signs x = + 6 +/- [sqrt (36 -12)/-6)] x = 6 +/- [sqrt (24)/-6] but sqrt 6 x sqrt of 4 = sqrt 24 hence x = 6 +/- [ sqrt 6 x sqrt 4 /-6] that is: x = 6 +/- [sqrt 6 x 2 /-6 ] so x = 6 + [sqrt 6 x 2/-6] and x = 6 - [sqrt 6 x 2/-6]
