Math Problem Statement

Simplify the expression by filling in the blanks: (7n^2 - 47n - 14) * (16n^2 - 56) / (14n^2 - 45n - 14).

Solution

Let's first analyze and simplify the expression from the image:

We are given the following expression to simplify:

(7n247n14)16n25614n245n14\left(7n^2 - 47n - 14\right) \cdot \frac{16n^2 - 56}{14n^2 - 45n - 14}

Step-by-step simplification:

  1. Factor the terms (if possible):

    • Let's first attempt factoring the quadratic terms in the expression.

    Factor the numerator 16n25616n^2 - 56: 16n256=16(n23.5)16n^2 - 56 = 16(n^2 - 3.5) This expression cannot be factored further in a simple manner, so we can leave it as is.

    Factor the denominator 14n245n1414n^2 - 45n - 14: This expression is a quadratic that can be factored using the method of splitting the middle term.

    Factor 14n245n1414n^2 - 45n - 14: 14n245n14=(7n+2)(2n7)14n^2 - 45n - 14 = (7n + 2)(2n - 7)

  2. Combine the simplified terms: The overall expression becomes: (7n247n14)16(n23.5)(7n+2)(2n7)(7n^2 - 47n - 14) \cdot \frac{16(n^2 - 3.5)}{(7n + 2)(2n - 7)}
