Find a quadratic function with roots x = 7 and x = -1.

The quadratic function with roots x = 7 and x = -1 is

Solution:

Given that , roots of a quadratic equation are x = 7 and x = - 1 .

We have to find the equation of that quadratic function.

Now, we know that, quadratic equation is given by

where a and b are roots of that quadratic equation

Here a = 7 and b = -1

By substituting the values in general equation, we get

Thus the required quadratic function is found
