How would you complete the square for this problem:
f(x)=x^2-x+(5/4)
There doesnt seem to be a way to do it:
(x^2-x+1-1)+(5/4)
(x^2-x+1)+(1/4)
So you have to factor the trinomial:
It doesnt work if yo
Okay, so I have two questions. First one:
Insert parenthesis in the following equations to make them true, prove your answers.
Example: Given; 21+13-17=35, you would insert parenthesis so it looks li
In quadrilateral STAR, one pair of opposite sides and one pair of opposite angles are _____ and _____.
ST and TA, angle S and angle A
ST and RA, angle S and angle T
TA and AR, angle T and angle R

If the total interest earned for the year was $680, how much was invested at each rate?-x*0.04 + (14,000-x)*0.08 = 680
-0.04x = -440
x = $11,000 @ 4%
and $3,000 @ 8%
f(x) = (3-sqrt(x)) / (x-9)
If g(x) was the result of the simplification, would the domains be the same?-(3-√x) / (x-9)
multiply both the numerator and denominator by (3+√x) we get,
[(3-√x)(3+√x)]/ (x
How do I calculate the limit of this problem.
lim x-->infinity sum of (-2/3)^k (upper limit n, k=2)
I am not english and hopefully nothing is lost in the translation. thanks-This is an infinite sum

Please answer this question, and show me what you did to get your answer. Thank you!
Simplify this expression.
(-3) ^2 + 12*4-(-3)^2 + 12*4 = (-3) * (-3) + 48=9 + 48 = 57

For this problem, assume the balls in the box
are numbered 1 through 6, and that an experiment consists of randomly
selecting 3 balls one after another without replacement.
What probability should be
If the question is (3x)^4 you would do 3^4 times x^4 so the problem would turn into 81x^4-(a b)^c = a^c * b^c
(a^b)^c = a^(bc)
Your example
(3x)^4 = 3^4 x^4 = 81 x^4
. . . note that (3x)*4 is NOT
7/8x + 3/4 = 1/2x + 3/2
I dont even know where to start.
Would you multiply the entire equation
by 8/7? o-O??
Please explain! I already know the answer.-7/8x+3/4=1/2x+3/2-3/4-3/4
7/8x=1/2x+3/4
-1/2x
