Question

help.  find the roots  for 5x2+8x-60-5=4x2
(those x's are squared)

anonymous · Answer

start by moving all terms with variables to the left side

One of the neat things here is the equation editor or through direct typing of LaTeX code for MathML:

$(\ $5x^2+8x-60-5=4x^2\) becomes: $ 5x^2+8x-60-5=4x^2$
And if you use [ ] at the start and end instead of ( ) it makes the equation a separate line.

Just thought I would bring it up since this is your first question and you were describing what was squared.

Thank you e. mccormick...I was searching online to figure out how to do that so my equation didn't look stupid!

anonymous · Answer

the solution the teacher gave was x=13  x=5   I got x=13  x= -5    any idea's on which one is correct?

anonymous · Answer

neither, but it is only a sign on your answer. It must be x=-13 and x=5. Did you use the general formula or factorization?
