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.
What statements should you include in your program to ensure that, when a number of type double is output, it will be output in ordinary notation with three digits after the decimal point?
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.
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 \(C++\) program that asks the user for a number of gallons and then outputs the equivalent number of liters. There are 3.78533 liters in a gallon. Use a declared constant. since this is just an exercise, you need not have any comments in your program.
