Answer:
The quadratic function x^2 -3x + 40 has roots x=8 and x= -5.
Step-by-step explanation:
If a polynomial has roots x=8 and x=-5, then we know that the factorized form is:
(x-8)(x+5)
So, to find the polynomial we need to expand the polynomials:
(x-8)(x+5) = (x^2 +5x - 8x + 40) = x^2 -3x + 40
Answer:
x² - 3x - 40 = 0
Step-by-step explanation:
The roots are x=8 and x= -5
The quadratic equation will be;
(x-8)(x+5) = 0
Therefore;
x² - 8x + 5x -40 = 0
x² - 3x - 40 = 0
