Problem

Solve the system of equations using technology: \[ \begin{array}{l} y=(4 x-1)^{2}-1 \\ y=-4 x+1 \end{array} \]

Solution

Step 1 :Set the two equations equal to each other: \( (4x - 1)^2 - 1 = -4x + 1 \)

Step 2 :Solve for x: \( x = \frac{1}{8} - \frac{\sqrt{5}}{8} \) and \( x = \frac{1}{8} + \frac{\sqrt{5}}{8} \)

Step 3 :Plug the x values back into either equation to find the corresponding y values: \( y = \frac{1}{2} + \frac{\sqrt{5}}{2} \) and \( y = \frac{1}{2} - \frac{\sqrt{5}}{2} \)

Step 4 :\( \boxed{\text{Final Answer: } (\frac{1}{8} - \frac{\sqrt{5}}{8}, \frac{1}{2} + \frac{\sqrt{5}}{2}) \text{ and } (\frac{1}{8} + \frac{\sqrt{5}}{8}, \frac{1}{2} - \frac{\sqrt{5}}{2})} \)
