1. Show how to create a numeric vector that contains the sequence from 20 to 50 by 5.
c<- seq(20, 50, 5)
c

1. Create the function “factorial” that takes a trio of input numbers a, b, and c and solve the quadratic equation. The function should print as output the two solutions.
FactiorialFunction <- function(a,b,c) {
x1 <- (-b+((b^2)-4*a*c)^0.5)/(2*a)
x2 <- (-b-((b^2)-4*a*c)^0.5)/(2*a)

FactiorialFunction(4,53,2)
