Use the zero product property to find the solutions to the equation x2 - 15x - 100 = 0.
Solution:
It is given that,
The zero product property must be used to find the solutions to the equation x2 - 15x - 100 = 0,
Now,
Look for 2 numbers that when you multiply them, obtain the result -100 and when you add them, obtain the result -15.
Let x2 - 15x - 100 = 0
x2 - 20x + 5x - 100 = 0
Now, take out common terms,
x(x - 20) + 5(x - 20) = 0
(x - 20) (x + 5) = 0
Then,
Equating both the factors with 0 to calculate the value of x, we get
x - 20 = 0, x + 5 = 0
x = 20, x = -5
Therefore, the solution to the equation is x = 20 or x = - 5.
Use the zero product property to find the solutions to the equation x2 - 15x - 100 = 0.
Summary:
By using the zero product property, the solutions to the equation x2 - 15x - 100 = 0 is x = 20 or x = - 5.
