3(m )(m )
Are we factoring?
I can't find the 2 numbers):
Can someone please help me?
Well break up into two equations, but keep the 3 with the x
so like I did a bit ago? 3(m )(m ) ?
I can help :)
Btw you can always use the quadratic formula
It just doesn't make much sense to me):
Alright- First step is quadratic formula. Have you heard of this?
We want to make a box that looks like the following:
You can factor without it though @Lagoonabarbie
I just don't get how I can find the two numbers using the quadratic formula... not the best at math, sorry
Okay. Since quadratic formula is very important to know, I will show you it that way. Just stay on this chat it might take a few minutes to show you the steps for this problem.
First, you need to use the two numbers- They are 3, (Which I get from 3m^2), and -4, which I get from the last part of the equation. We are going to be using -12, (The product of -4 and 3)
use those numbers for what?
I'm sorry. We want to use 11. Not 4.
I'm drawing it. One minute! :)
So- How can we get two of the same numbers that multiply to 33, and add to 11?
The 33 comes from the 3 (in the 3m^2), and the 11 comes from the (11x)
I tried to solve it and I just couldn't do the formula, my calculator said error...
oh ok, i see what youre doing
but why 33?
Under the 33, you want to find two numbers that multiply to 33, AND the same numbers have to ADD to 11.
33 comes from
3 x 11
comes from the 3, yeah but why times 11?
That is just the way you solve the problem :)
so a times b?
So- Looking back on the picture I just posted, can you find two of the same numbers that multiply to 33, and add to 11?
And- Correct. A x B. Exactly
no, i cant figure it out...
Exactly! That means, there is no solution! It is impossible.
so it's trying to trick me or something?
Nope! A lot of times in math they throw in those 'No Solution' problems.
Let me check my work before you close the problem..
So do I just say "no solution"?
Don't write it yet.
The math in one of the steps is incorrect. I will upload a picture of my new work in one moment.
but does the answer stay the same?
There will be an answer, actually. It will look something like: (3x-2)^2
calculator says "no solution" ...
I'm sorry. The answer is no solution. Sorry to keep you waiting. I just had to double check. :) Good luck!!
no worries, thank you for helping me!
