@mathmate This is part of a pre test so i know nothing about it. but if i pass the pre test i can skip the lesson.

will the solution are -3 and 1
the function should be written like this f(x)=(x+3)(x-1)

xapproachesinfinity · Answer

if you solve this equation x^2+2x-3=0 you should get those solutions

If you know nothing about the subject, your best option is one of the following:
1. learn enough so you can pass the test
2. take the lesson.
For most people, the second option is the most efficient.  This is the purpose of the pre-test.  Skipping it will make your future learn more difficult, if possible at all.

anonymous · Answer

well they give you the option to take the pre test and if you pass it then you dont have to go through the lesson. that was the only one i got stuck on but i wanted help just incase i got some wrong.

The solution to f(x) is exactly where it crosses the x-axis.
