The polynomial f(x)= -x³ - 7x² - 7x + 15 has zeros located at -5, -3, 1 because f(-5) = f(-3) = f(1) = 0
An equation is an expression that shows the relationship between two or more numbers and variables.
The function f(x)= -x³ - 7x² - 7x + 15 has zeros located at -5, -3, 1, hence:
f(-5) = -(-5)³ - 7(-5)² - 7(-5) + 15 = 0
f(-3) = -(-3)³ - 7(-3)² - 7(-3) + 15 = 0
f(1) = -(1)³ - 7(1)² - 7(1) + 15 = 0
The polynomial f(x)= -x³ - 7x² - 7x + 15 has zeros located at -5, -3, 1 because f(-5) = f(-3) = f(1) = 0
