Other quadratic equations have no real solutions; for example, x squared, + x, + 5 = 0. In this case, the expression under the square root symbol is negative, so the entire expression is not a real number. Some quadratic equations can be solved more quickly by factoring. For example, the quadratic equation 2, x squared, minus x, minus 6 = 0 in ...

one real solution, two real solutions or no real solutions. Example #1: Graph y = x 2 + 2. Tell how many solutions the graph will have.This is a vertical shift of y = x 2 up 2 units. Note: When moving the graph 2 units up, we no longer have x-intercepts. Therefore, this function will have NO REAL SOLUTIONS.

example: Solve by completing the square. [Recall that we tried to solve this equation graphically and concluded that there are no real solutions. Thus, we should expect that our solutions will be complex numbers.] SOLUTION: First, we need to find the square of half the coefficient of the linear term (in this case, the coefficient of x):
