Question

X2 -2x + 1 = 0 solve quadratic equations graphically with a table

Answer 1

Given:

`\begin{gathered} x^2-2x\text{ +1 = 0} \\ The\text{ solution to this equation will be the x values that result in f\lparen x\rparen =0} \end{gathered}`

To solve, we can use a table of values:

Y valueX value

16-3

9-2

4-1

10

01

12

As we can see from the table, f(x) =0 when x =1.

Thus x = 1 is a solution to our equation.
