Finding the Solution in a Quadratic Equation?
I'm back again with a few problems I'm stuck on. I'm really not sure where to go with them, or how to solve them. Unfortunately I'm a complete dunce when it comes to math, and only manage to get by with help from tutors and such. But these were a few problems that I didn't have time to ask at the tutor's...
I don't know if it makes any difference, but here are some of the instructions that were printed at the top of my paper...
Find the solution for each of the following equations.
1- Put the equation in form
2- Determine the form of the equation
3- Find the solutions
-Set each factor equal to 0 and solve
-Solve using the square root method ( )
-Solve by factoring
-Use the Quadratic Equation
Most of the problems are the form, and I know that if there is nothing that adds to B and multiplies to C (or maybe it's the other way around) that I need to use the square root method, which is different for me as before we were just told to write "no solution". This time I guess we have to continue it.
I've got most of the problems solved, but there's still a few I'm struggling with and I'm not sure where to go with them. They're probably easier than I think they are, so I'm probably over-thinking things, but...
For this, do I just bring the 0 over and than add the 0 back in at the end as well, and than solve, or is it something different?
Though I guess bringing over the 0 doesn't make much sense, now that I think about it...
I'm really not sure where to go with this one, as it has no Bx and such...
Also, for a couple problems I finished I'm just not sure if I got the correct answer. Would anyone be willing to just look them over for me and tell me whether I got them right or wrong?
Any help or advice would be very much appreciated. Thank you! :)
