Math Problem Statement

x^2-5x-14/x^2+4x+4

Solution

It seems like you have the expression:

x25x14x2+4x+4\frac{x^2 - 5x - 14}{x^2 + 4x + 4}

Would you like to simplify this expression, factor it, or solve for specific values of xx? Let me know what you're looking for!

If you’d like to factor both the numerator and the denominator:

Factoring the denominator:

The denominator is x2+4x+4x^2 + 4x + 4, which is a perfect square trinomial:

x2+4x+4=(x+2)2x^2 + 4x + 4 = (x + 2)^2

Factoring the numerator:

For the numerator, x25x14x^2 - 5x - 14, we look for two numbers that multiply to 14-14 and add up to 5-5. These numbers are 7-7 and 22, so we can factor it as:

x25x14=(x7)(x+2)x^2 - 5x - 14 = (x - 7)(x + 2)

Now, the expression becomes:

(x7)(x+2)(x+2)2\frac{(x - 7)(x + 2)}{(x + 2)^2}

Simplification:

You can cancel the common factor of (x+2)(x + 2) in the numerator and denominator (as long as x2x \neq -2, since division by zero is undefined):

x7x+2\frac{x - 7}{x + 2}

So, the simplified expression is:

x7x+2\frac{x - 7}{x + 2}

Would you like more details on this process, or do you need help with another step?
