Solutions

Chapter 2, Problem 6RE
To determine

The value of limx1+x29x2+2x3.

Expert Solution

Answer to Problem 6RE

The value of limx1+x29x2+2x3=.

Explanation of Solution

Express the given function as follows.

limx1+x29x2+2x3=limx1+x29x2+2x3=limx1+(x+3)(x3)(x+3)(x1)=limx1+(x3)(x1)

Since x is closer to 1 from right side (that is, x>1), the denominator (x1) is a small positive number (=0) and the numerator (x3) is a negative number.

Hence, the quotient is a numerically larger negative number.

Therefore, it can be concluded that, limx1+x29x2+2x3=.
