C++ The roots of the quadratic equation ax² + bx + c = 0, a ≠ 0 are given by the following formula: In this formula, the term b² - 4ac is called the discriminant. If b² - 4ac = 0, then the equation has a single (repeated) root. If b² - 4ac > 0, the equation has two real roots. If b² - 4ac < 0, the equation has two complex roots. Instructions Write a program that prompts the...

Write a function that determines the real roots of a quadratic equation ax2 + bx + c = 0. To calculate the roots of the equation, the function calculates the discriminant D, given by: D = b2-4ac If D> 0, the code should display "The equation has two roots" and print the values on a new line. If D 0, the code should display "The equation has one root.", and print the value on...

At least one of the answers above is NOT correct. (1 point) Suppose /(x) = x + 3x + 1. In this problem, we will show that has exactly one root (or zero) in the interval (-3,-1). (a) First, we show that f has a root in the interval (-3,-1). Since is a continuous function on the interval (-3, -1) and f(-3) = and f(-1) = -1 the graph of y = f(x) must cross the X-axis at some point...
