Problem
Pre-Test Active 1 2 3 4 5 6 7 8 9 10 TIME REMAINING $38: 22$ A polynomial is factored using algebra tiles. Which polynomial was factored? $x^{2}-2 x-8$ $x^{2}+2 x-8$ $x^{2}-2 x-4$ $x^{2}+2 x-4$
Solution
Step 1 ：Let's check each option by finding their factors.
Step 2 ：Factored polynomials: (x - 4)*(x + 2), (x - 2)*(x + 4), x**2 - 2*x - 4, x**2 + 2*x - 4
Step 3 ：Final Answer: The polynomial that was factored is \(\boxed{x^{2}-2 x-8}\)
