3(-2x+5)+(-2x+5)(x-3): Simplifying Algebraic Expressions

In this article, we will explore how to simplify the algebraic expression 3(-2x+5)+(-2x+5)(x-3). Algebraic expressions are a fundamental concept in mathematics, and simplifying them is an essential skill to master.

Breaking Down the Expression

Let's break down the given expression into its components:

  • 3(-2x+5): This is a term with a coefficient of 3, and a binomial expression -2x+5 inside the parentheses.
  • (-2x+5)(x-3): This is a product of two binomial expressions, -2x+5 and x-3.

Simplifying the Expression

To simplify the expression, we will follow the order of operations (PEMDAS):

Step 1: Evaluate the expression inside the parentheses

  • 3(-2x+5) = 3(-2x) + 3(5) = -6x + 15
  • (-2x+5)(x-3) = -2x^2 + 6x - 15x + 45 = -2x^2 - 9x + 45

Step 2: Combine like terms

Now, we combine the two expressions:

-6x + 15 - 2x^2 - 9x + 45

Step 3: Simplify the expression

Combine like terms:

-2x^2 - 15x + 60

And that's the simplified expression!

Conclusion

In this article, we have successfully simplified the algebraic expression 3(-2x+5)+(-2x+5)(x-3) using the order of operations and combining like terms. The final simplified expression is -2x^2 - 15x + 60.
