Question

what is the quadratic polynomual whose zeroes are 3 and -5 ?​

Answer 1

Answer:

$x^{2}$ + 2x - 15

Step-by-step explanation:

Sum of zeros = 3 + (-5)

                      =  3 - 5

                      = -2

Product of zeros = 3 x (-5)

                            = -15

Equation = k($x^{2}$ - sx + p)

               = k($x^{2}$ + 2x - 15)

.: Quad. Polynomial is $x^{2}$ + 2x - 15
