Answer: x = -5
Step-by-step explanation: To solve this equation, we start by distributing the -4 through the parentheses on the left side.
So we have -4 times x which is -20x and -4 times -5 which is positive 20. So our equation now reads -20x + 20 = 120.
Solving from here, we subtract 20 from both sides of the equation and we have -20x = 100 and dividing both sides by -20, we find that x = -5.
Although I will not provide work to check our answer, the great thing about solving equations is that your can always check your answer by substituting what you got as a final answer into the original equation.
<span>The function is undefined when x = 3.
You have a function where the numerator is 1 and the denominator is an expression with the variable x. That function will be undefined at those points where the denominator has a value of zero. So let's look at just that part of the function and solve it for where its value is zero.
(x-5)^2 + 4(x-5) + 4 = 0
Perform the squaring of (x-5)
x^2 - 10x + 25 + 4(x-5) + 4 = 0
Distribute the 4
x^2 - 10x + 25 + 4x - 20 + 4 = 0
Combine common terms (add -10x to 4x, and add 25 to -20 to 4)
x^2 - 6x + 9 = 0
We now have a quadratic equation with a=1, b = -6, and c=9. Solve using the quadratic formula, giving a root of x = 3.
Verify by seeing if x=3 gives a denominator of 0..
(x-5)^2 + 4(x-5) + 4 = y
(3-5)^2 + 4(3-5) + 4 = y
(-2)^2 + 4(-2) + 4 = y
4 + -8 + 4 = y
0 = y</span>
