What is the value of the rational expression 2x^2+5x+9/x^2+2x-1 when x=-2

The value of the Rational expression when is:

Step-by-step explanation:

For this exercise is important to remember:

Then, given the following Rational expression:

You need to follow these steps in order to find its value when :

1. Substitute the given value of "x" () into the expression:

2. Evaluate and simplify:

(4,5

look up a corrdinate plane and do what the thingy says and boom

logv3(x+2)=1

rewrite in exponential form:

logb(x) = y is equal to b^y =x

b = 3, y = 1

now solve for x:

3^1 = x+2)

x = 3-2

x = 1
