Facoring if possible. Completing the Square or the Quadratic Formula, otherwise.

You've probably done it 100 times, already. Solve this for x: x + 2 = 0

Try this one: \(x^{2}  1 = 0\)

You've been studying factoring and the Quadratic Formula. Now is the time to use these skills and tools!

(2.*(x+2.271633299))*(x.3422414369)*(x1.929391862)

so you factor to get (2.*(x+2.271633299))*(x.3422414369)*(x1.929391862)=0 get rid of 2 by dividing (x+2.271633299)*(x.3422414369)*(x1.929391862)=0 Then you just solve individually (x+2.271633299)=0 > x=2.27... (x.3422414369)=0 > x= .34... (x1.929391862)=0 > x=1.92...

Is it really \(x^{3}\) and not \(x^{2}\)?
