Question

Find the roots of the function

            (2x^2-5x+1)

f(x)=11^                   -1

Express your answer in exact form.

Answer 1

           (2x^2-5x+1)
f(x)=11^                   -1

 

To find the roots, set f(x) to zero:

 

       (2x^2-5x+1)
0 =11^                 -1

 

         (2x^2-5x+1)
1 =11^

 

Remember that 11⁰ = 1, so we must have:

 

2x² - 5x + 1 = 0

 

Use the quadratic formula to solve for x.
