Math Problem Statement

Write a quadratic function with zeros -8 and -6. Write your answer using the variable x and in standard form with a leading coefficient of 1.

Solution

The problem asks you to write a quadratic function with zeros 8-8 and 6-6.

A quadratic function can be expressed in factored form as: f(x)=a(xr1)(xr2)f(x) = a(x - r_1)(x - r_2) where r1r_1 and r2r_2 are the zeros of the function. In this case, r1=8r_1 = -8 and r2=6r_2 = -6, and the leading coefficient aa is given as 1.

So, the factored form of the quadratic is: f(x)=(x+8)(x+6)f(x) = (x + 8)(x + 6)

Now, expand the expression to get it in standard form: f(x)=(x+8)(x+6)=x2+6x+8x+48=x2+14x+48f(x) = (x + 8)(x + 6) = x^2 + 6x + 8x + 48 = x^2 + 14x + 48

Thus, the quadratic function is: f(x)=x2+14x+48f(x) = x^2 + 14x + 48
