Answer: 4n + 2 = -18 and n= -5
Step-by-step explanation:
4 times a number is the same as the expression, 4n where n is the number and two more than that is 4n + 2. If it is -18, then it means it is equal to -18.
4n + 2 = -18 You can solve for a by subtracting -2 from both sides
-2 -2
4n = -20 Divide both sides by 4.
n = -5
It's vertex form for a quadratic function =D
