solve for x
OpenStudy (anonymous):
x=1 and x=-2/5
OpenStudy (anonymous):
That is what I thought, but how did you come up with -2/5?
OpenStudy (zehanz):
You have an equation of the form \(a \cdot b=0\). To solve it, break it up into: \(a=0\) or \(b=0\). Then solve each of these separately.
OpenStudy (anonymous):
2x+5=0 hence 2x=-5 and x=-5/2
