$\%$ Don't change the variable names

$\%$Part $A$

$a=2$;$b=8$;$c=8$

$xa=\%$ Use variable $\text{'}xa\text{'}$ for one real root

$1a=\%$ Use variables $\text{'}1a^{\text{'}}$ and $\text{'}2a\text{'}$ for $2$ distinct roots

$2a=$

$\%$Part $B$

$a=-5$;$b=3$;$c=-4$

$xb=$ oUse variable $\text{'}xb\text{'}$ for one real root

$x1b=\%$ Use variables $\text{'}1b\text{'}$ and $\text{'}2b\text{'}$ for $2$ distinct roots

$x2b=$

poPart $C$

$a=-2$;$b=7$;$c=4$

$xc=\%$ Use variable $\text{'}xc\text{'}$ for one real root

$x1c=\%$ Use variables $\text{'}x1c\text{'}$ and $\text{'}2c\text{'}$ for $2$ distinct roots

$x2c=$Write a program that determines the real roots of a quadratic equation. To calculate the roots of the equation the program calculates the discriminant $D,$ given by: $D=b^2-4ac.$

If $D>0,$ the program displays message "The equation has two roots," and the roots are displayed in the next line.

If $D=0,$ the program displays message "The equation has one root," and the root is displayed in the next line.

If the program displays message "The equation has no real roots."

Run the program to obtain solutions to the following three equations:

a$)2x^2+8x+8=0$

b$)-5x^2+3x-4=0$

c$)-2x^2+7x+4=0$
