Answer:
a. (x^3+8)(x^2-4)
b. x=1 and x=1/2
Step-by-step explanation:
a. (x^3+8)(x^2-4) = x^5-4x^3+8x^2-32 [foil method: first,outside,inside,last]
b. use quadratic formula: -b +/- square root b^2-4ac / 2a
2=a; -3=b; 1=c
-(-3) + square root (-3)^2 - 4(2)(1) / 2(2)
3 + 1 / 4 = 4/4 = 1
3 - 1/4 = 2/4 = 1/2
This expression of yours is problematic in that it's difficult to know which math operations are intended and in which order. In <span>x/2 x-2/4 x-2/2 , which part of the expression is in the numerator, and which in the denominator?
x shows up 3 times. Apparently you meant "the variable x" in "x/2." What about the next "x?" Did you type that in to indicate multiplication or is that "x" a variable also? I think you catch my drift: Your post will need some editing before your readers can understand what you want to do here.
Suppose I interpret your </span><span>x/2 x-2/4 x-2/2 to mean the following:
( x/2 )
---------- * (x-2/2). If that wasn't your intent, please fix it.
x - 2/4
If this interpretation is correct, then you have
x(x-1) 2x(x-1)
---------------- = ------------. If not, please fix it. This rational function
x-1/2 2x -1 cannot be reduced.</span>
