Get started for freeConsider a quadratic expression, say \\[ x^{2}-x-2 \\] Describing where this quadratic is positive (that is, greater than 0 ). involves describing a set of numbers that are either less than the smaller root (which is -1 ) or greater than the larger root (which is +2 ). Write a \(\mathrm{C}++\) Boolean expression that is true when this formula has positive values.
Give a \(\mathrm{C}++\) statement that will change the value of the variable sum to the sum of the values in the variables \(n 1\) and \(n 2\). The variables are all of type int.
Write a complete \(\mathrm{C}++\) program that reads in two whole numbers and outputs their sum. Be sure to prompt for input, echo input, and label all output.
Give an output statement that will produce the following message on the screen: The answer to the question of Life, the Universe, and Everything is 42
Consider the quadratic expression \\[ x^{2}-4 x+3 \\] Describing where this quadratic is negative involves describing a set of numbers that are simultaneously greater than the smaller root (+1) and less than the larger root \((+3) .\) Write a \(\mathrm{C}++\) Boolean expression that is true when the value of this quadratic is negative.
