Question

Given f(x) and g(x), find all values of x for which f(x) = g(x).
f(x)=x^2-6 and g(x)=10x-28
x=??
simplify, using radicals as needed.

Answer 1

x^2-6=10x-28
x^2-10x+22=0
x=10\[x=(10\pm \sqrt{12})/2=2\pm \sqrt{3}\]

Answer 2

I'm a little confused by this answer... why is ther two equal signs in it??
