You first get the constant numbers to the opposite side of the x^2, so get the -5 to the other side.
x^2 - 10x = 14 do you understand this, so far?
got it!!!!!! thank you so much!

what did you get for an answer?
x=+- square root of 39?
x=5+_ square root of 39
x^2 - 10x + 25 = 14 + 25 (x - 10)^2 = 39 x - 10 = +-sqrt(39) x = +- sqrt(39) + 10
whered you get the 10 from?
it factors to (x-5)^2
OOPS you are correct....
haha no worries
but then you need to add 5 to both sides... x = +-sqrt(39) + 5 sorry I was texting and doing math at the same time.
blexting can you help with a few more questions?
Sure
M: 2/m + 3/m+9= 11/4
You need to find a common denominator.. is the + 9 in the denominator or all by itself?
m+9
So the denominators are m and m + 9 and 4 so your common denominator is 4m(m+9) do you agree?
yes i agreee!!!
so we multiply everything by that correct?
top and bottom?
8(m+9)+12m =......
Because you have denominators and an equal sign. you need to multiply each term by your common denominator. 4m(m+9)*2/m + 4m(m+9) * 3/(m+9) = 4m(m+9)*11/4
Cancel the denominators into the numerators
4(m+9)*2 + 4m*3 = m(m+9)*11
8(m+9) + 12m = 11m(m+9)
8m + 72 + 12m = 11m^2 + 99m
Because you have an equal sign and an x^2 term you need to put the other side = to 0.
0 = 11m^2 + 79m - 72
I would use the quadratic formula here.. Do you agree with my steps so far?
0 = (11m + 9)(m +8) m = -9/11 or -8 sorry it factors.
im confuseddd ahhhhhhh i got 10.5
i think i got it!
omg got it!
Great...
i <3 you
wanna be our math tutor for the night? i have another problem :D
Sure... for awhile.
