Find a quadratic function with roots x = 8 and x = 9.

The quadratic function with roots x = 8 and x = 9 is given as

Solution:

Given that the roots of function are x = 8 and x = 9

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 = 8 and b = 9

By substituting the "a" and "b" values in general quadratic function we get,

Hence the required quadratic function is found out
