The quadratic equation has two complex solutions
Step-by-step explanation:
we know that
The formula to solve a quadratic equation of the form
is equal to
in this problem we have
Equate to cero
so
substitute in the formula
Remember that

so
therefore
The quadratic equation has two complex solutions
I must assume that your graph is that of a straight line, and that the end points of the line are P and B, and (finally) that T is between P and B. If these assumptions are correct, then the length of the line segment PB connecting points P and B is 15 + 10, or 25.
The total area is 448 in^2. Each triangle is 56 in^2 and each parallelogram is 140 in^2
