Print numbers with under square root symbol

Question

I have to print the output of my solution(quadratic equation) in below format: Quadratic Equation Format

I have the numeric values and can print the square root symbol using "Square Root: \u221A".

However, I have no clue on how to insert numbers with a root symbol over it and also an underlined division sign as shown in image above.

Please suggest any feasible approach or workaround for this. Thanks!

There's no native support for equations in Android. You could use MathJax (https://www.mathjax.org/) within a WebView, or a possibly a better option is jqMath, see here:

Finally got it working using MathView.

It's a custom view library based on Android WebView and use MathJax to display math formula.

The setup is pretty straight forward too and is specifically developed for Android apps.

<io.github.kexanie.library.MathView
    android:id="@+id/formula_one"
    android:layout_width="match_parent"
    android:layout_height="wrap_content"
    auto:text="When \\(a \\ne 0\\), there are two solutions to \\(ax^2 + bx + c = 0\\)
            and they are $$x = {-b \\pm \\sqrt{b^2-4ac} \\over 2a}.$$"
