So I made this program to solve the quadratic formula. This program also displays the discriminant of the quadratic formula. the formula is this (-B ± √(B^2 -4AC))/2A and the discriminant is B^2 -4AC. For some reason, the program only will spit out the correct answers when A is 1. There are no syntax errors that will prevent the code from running. Can I have a fresh set of eyes look at it?
Prompt A
Prompt B
Prompt C
(B)²-4AC→Z
(B-√(Z))→Y
(B+√(Z))→X
Disp "DISCRIMINANT"
Disp Z
Disp "X: "
(X)/2*A→D
(Y)/2*A→E
Disp D,E

I see two issues with your code.
- You're using
B, not-B - You're doing
/2*A, not/(2*A). The ti83/84 family of calculators evaluates multiplication and division strictly from left to right. So/2*Ais "divide by two, then multiply by A".
I would cleanup your code as follows:
Prompt A,B,C
B²-4AC→Z
Disp "DISCRIMINANT:", Z
-B-√(Z)→Y
-B+√(Z)→X
X/(2A)→D
Y/(2A)→E
Disp "X:",D,E
