write a program that returns the zeros of a polynomial formula when the user enters it in javascript

index.tsx
function findZeros() {
  // Get the polynomial formula from the user
  let poly = prompt("Enter the polynomial formula:");

  // Parse the formula into a function
  let polyFunction = new Function("x", "return " + poly);

  // Find the zeros using the Newton-Raphson method
  let x0 = 1.0;  // Starting value
  let tolerance = 1e-6;  // Desired accuracy
  let numIterations = 100;  // Maximum number of iterations
  let x = x0;
  let fx = polyFunction(x);
  let dx = 0.0;

  for (let i = 0; i < numIterations; i++) {
    let fpx = (polyFunction(x + tolerance) - fx) / tolerance;
    dx = -fx / fpx;
    x += dx;
    fx = polyFunction(x);

    if (Math.abs(dx) < tolerance && Math.abs(fx) < tolerance) {
      break;
    }
  }

  // Display the zeros to the user
  alert("The zeros of the polynomial are: " + x);
}
