Use function a script on matlab please!

Ask the user to enter the values for the three constants $(a,b,c)$ of the quadratic equation

$a{x}^2+bx+c=0$

Use an if$-$elseif$-$else$-$end structure to warm the user if $b^2-4ac>0,b^2-4ac=0,$ or If $b^2-4ac0,$ determine the solution x $1$ and x $2.$ Use the following to double$-$check the functionality of your function. Fill the answer in the blank.

a$)$ Use $a=1,b=2,c=-1($Keep $2$ digits after decimal point for your solutions$)$

$x1=$

$$

$x2=$

$$

b$)$ Use $a=1,b=2,c=1($using whole number here$)$

$x1=$

$$

$x2=$

$$

$A$

c$)$ Use $a=10,b=1,c=20$

What is the value $b^2-4ac=$

$$

A

Can you get $1,2$ with real number solution for case c
