Introduction

Simplifying complex algebraic expressions is a crucial skill in mathematics, particularly in calculus and algebra. It involves combining like terms, canceling out common factors, and rearranging the expression to make it more manageable. In this article, we will focus on simplifying the given expression: $\frac{t+1}{t-1}+\frac{2}{t^2-5t+4}$ . We will break down the expression into smaller parts, simplify each part, and then combine them to obtain the final simplified expression.

Factorization of the Denominator

The first step in simplifying the expression is to factorize the denominator of the second fraction. The denominator is $t^2-5t+4$ , which can be factored as $(t-1)(t-4)$ . This can be done by finding two numbers that multiply to $4$ and add to $-5$ . The numbers are $-4$ and $-1$ , so we can write the denominator as $(t-1)(t-4)$ .

Simplifying the Expression

Now that we have factored the denominator, we can rewrite the expression as $\frac{t+1}{t-1}+\frac{2}{(t-1)(t-4)}$ . We can simplify the expression by finding a common denominator, which is $(t-1)(t-4)$ . We can rewrite the first fraction as $\frac{(t+1)(t-4)}{(t-1)(t-4)}$ .

Combining the Fractions

Now that we have a common denominator, we can combine the fractions by adding the numerators. The expression becomes $\frac{(t+1)(t-4)+2}{(t-1)(t-4)}$ . We can simplify the numerator by expanding the product $(t+1)(t-4)$ .

Expanding the Product

The product $(t+1)(t-4)$ can be expanded as $t^2-3t-4$ . We can rewrite the expression as $\frac{t^2-3t-4+2}{(t-1)(t-4)}$ . We can simplify the numerator by combining like terms.

Simplifying the Numerator

The numerator $t^2-3t-4+2$ can be simplified as $t^2-3t-2$ . We can rewrite the expression as $\frac{t^2-3t-2}{(t-1)(t-4)}$ . We can simplify the expression further by factoring the numerator.

Factoring the Numerator

The numerator $t^2-3t-2$ can be factored as $(t-2)(t+1)$ . We can rewrite the expression as $\frac{(t-2)(t+1)}{(t-1)(t-4)}$ . We can simplify the expression further by canceling out common factors.

Canceling Out Common Factors

The expression $\frac{(t-2)(t+1)}{(t-1)(t-4)}$ can be simplified by canceling out the common factor $(t-1)$ . We can rewrite the expression as $\frac{(t-2)(t+1)}{(t-4)}$ . We can simplify the expression further by canceling out the common factor $(t+1)$ .

Final Simplified Expression

The final simplified expression is $\frac{t-2}{t-4}$ . This is the simplest form of the given expression.

Conclusion
