Quote:Finding the x intercepts, the below answer at the below link, step 7 in the first table.
I have been shown this way, and shown another way using the RHS with more manipulation.
Is this the easiest way?
Is this the only answer we can ever arrive at no matter how we calculate?
x=−2/3±(√−43/18)
that is,
x1,x2=−23±1/6 √(86i)
And where did the 1/'6th come from.

Stu:so the 1/6 is the square of 86 by 36?
Also can't we surd the 86? If yes, how would that work exactly given the 1/6 in front of the 86?
