Use the zero product property to find the solutions to the equation x^2-15x-100=0

or

Step-by-step explanation:

To solve the quadratic equation we must factor the expression

Look for 2 numbers that when you multiply them, obtain the result -100 and when you add them, obtain the result -15.

You can verify that these numbers are -20 and 5

Then the polynomial factors are

 The zero product property says that if two terms then

or
