Use the zero product property to find the solutions to the equation x^2-15x-100=0
7nadin3 [17]

Answer:

x = 20 or x = -5

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

-20 +5 = -15\\\\-20 * 5 = -100

Then the polynomial factors are

(x-20) (x + 5) = 0

 The zero product property says that if two terms a * b = 0 then

a = 0 or b = 0

So

(x-20) = 0 or (x + 5) = 0

x = 20 or x = -5
