One you have one zero, say x = 5.3 (invented example number)
Then divide the original polynomial by (x-5.3)
That leaves you with a quadratic, which you can solve with your calculator.
How do i solve the quadratic with my calculator. Thanks so much for your help:)
Use the quadratic equation
if
y = a x^2 + b x + c
then y is zero if
x = -b/2a +or- (1/2a)sqrt(b^2 - 4 a c)
