We are learning about parabolas and the question was using partial facotring to find 2 points that lie on the parabola. How would I do that? Ex. y=x^2-12x+23
when is partial factoring used?
Then when is partial factoring used?
can't you partial factor x^2+3x+9 x^2+3x=0 x(x+3)=0 x= 0 or x=-3 what am I doing wrong?
How would you find the zeroes for this? x^2+3x-9
This is how I did this: 5x^2+10x=20 <--- I left that out, sorry 5x^2+10x-20=0 5(x^2+2x)-20=0 5(x^2+2x-1+1)-20+5 5(x+1)^2-15=0 So I was thinking that (-1,-15) was the vertex because it is in the form y=a(x-h)^2+k ?? Does this make sense?
When completing the square: 5x^2 + 10x - 20 5 ( x^2 + 2x) -20 = 0 5 ( x + 1)^2 -15 = 0 Did I do that right? If so I have another question. When it's in this form, -15 is the y-coordinate of the vertex and 2 the x coordinate of the vertex? If so isnt the x cooridinate of ...
Thanks so much =]

The definition of aberrant means "deviation from the norm." Which means, if you had an aberrant day, your day was more unique and different than usual. I'm guessing that word in the sentence does make sense.
