About Zeros in the Denominator of Rational Expressions
One thing that you must be careful about when working with rational expressions is that the denominator can never be zero. Division by zero is undefined. So any values for the variables that would make the denominator zero must be excluded from the domain of the expression.
Let me show you what I mean by this. You should carefully study the following examples.
For the following, state the values of the variable that must be excluded from the rational expression:
2x -3/x2-3x-10
Solution: Again, exclude the values for which the denominator, or x2 - 3x - 10 = 0:x2 - 3x -10 = 0(x - 5)(x +2) = 0x - 5 = 0 or x + 2= 0x = 5 or -2So this means that x = 5 and x = -2.
You''ve decided you want a plant for your room. At the gardening store, there are 444 different kinds of plants (tulip, fern, cactus, and ficus) and 444 different kinds of pots to
Ut=Uxx+A exp(-bx) u(x,0)=A/b^2(1-exp(-bx)) u(0,t)=0 u(1,t)=-A/b^2 exp(-b)
Horizontal tangents for Parametric Equations Horizontal tangents will take place where the derivative is zero and meaning of this is that we'll get horizontal tangent at value
x^2-5x+4 can written in roots as (x-1)*(x-4) x^2-4 can be written interms of (x-2)(x+2).so [(x-1)(x-4)/(x-2)(x+2)]
2cos^2x-sinx=1......Find x
Find out the volume of the solid obtained by rotating the region bounded by y = (x -1) ( x - 3) 2 and the x-axis about the y-axis. Solution Let's first graph the bounded r
do we calculate midpoints from classes or from class boundaries
sin3θ = cos2θ find the most general values of θ satisfying the equatios? sinax + cosbx = 0 solve ? Solution) sin (3x) = sin(2x + x) = sin(2x)cos(x) + cos(2x)sin(x) = 2sin(x)cos(
how do we figure it out here is an example 3,4,6,9,_,_,_,_,_,. please help
