The answer is 3. 20/2=10 10-7=3
F(x)= (x+13)(x-2) in expanded form, it would be x^2+11x-26
First, multiply 5 • x, which is 5x. Then, multiply 5 • 1, which is 5. Now you have the equation 5x + 5 = -20. Now, subtract 5 from +5 and do the same to the -20, which gets you -25. Now divide -25 by 5, which is -5. Therefor, x= -5. Check by multiplying -5 • 5, which is -25. Then add -25 + 5, which is 20 and you now know your answer is correct.
Final Answer: x = -5
