The quadratic function with roots x = 3 and x = -8 is

Solution:

Given that the roots are x = 3 and x = -8

We need to find the quadratic function

Now, we know that, quadratic equation is given by

where a and b are roots of that quadratic equation.

Here a = 3 and b = -8

So now our quadratic equation is obtained by substituting "a" and "b" values in general equation

Hence the required quadratic function is found out
