Hi,
I am having problems with my homework. As I have this one math problem
that is just bugging the hell outta me and I cannot figure it out for
the life of me.
1)x-2x-1 =0
Find both roots. You must simplify both of your roots. This equation requires
the use of the Quadratic Formula. I have tried everything for this and
I am still either getting the wrong answers, and end up getting really
frustrated. If you could find the answers and tell me how you did it I
would greatly appreciate it! Then the second problem is
2) The square of a certain negative number is equal to 70 decreased by
3 times the number. Find the answer! On this one I set it up but still
came out with the wrong answer. So if you could help me on this one I
would greatly appreciate it!
Sincerely,
Katie
Hi Katie,
Is the first problem x2-2x-1=0? If so then by the quadratic formula I get
For the second problem if the number is x then
