Answer:
x² - 2x - 15
Step-by-step explanation:
There are two ways for solving this question
Way 1:
Find the sum and product of zeroes, put it in the polynomial formula and get the equation.
Sum of zeroes = 5 + (-3) = 2
Product of zeros = 5(-3) = -15
Formula = x² - (sum)x + product
→ x² - 2x - 15
Way 2:
Find the factors anmutiply them to get the equation
x = -3 → x + 3 = 0
x = 5 → x - 5 = 0
Equation = (x+3)(x-5) = x² + 3x - 5x - 15
→ x² - 2x - 15
