My assigned equations this week are the two in number 8. I'm fighting my millionth sinus infection this summer currently, so I do apologize for my delayed post: In Problem 2, solve by using the quadratic formula. Give solutions exactly and as decimal accurate to the nearest thousandth. Problem 2: 2x2 + x - 16 = 0 First, I have to find the values of a, b, and c in this equation formax2 + bx + c = 0: a = 2, b = 1, and c = (- 16) Now, we substitute, or "plug-in" the values into the quadratic formula, which is: x = b bb24ac 2a The next step is to determine the discriminant (D), which is the expression b2 4ac In this equation, it becomes D = 1 - 4(2) ( - 16) = 1 + 128 = 129. Using the values of a, b, c, and the discriminant (D), I'll use the quadratic formula to find the solutions for x. The formula is x = (-b D) / (2a), providing solutions for x and x: x = (-1 + 129)/4, and x = (-1 - 129)/4: x 2.766, x -5.766 when rounded to the nearest thousandths
