EQUATION CALCULATIONS

To start a EQN calculation, perform key operation
MODE 5 (EQN) to enter EQN MODE as below:

1= Simultaneous linear equation with 2 unknowns
2= Simultaneous linear equation with 3 unknowns
3= Quadratic equation
4= Qubic equation



Solve for 2x2  x  3  0

Step Action
1 MODE 5 to enter EQN mode

2 3 to choose QUADRATIC form
Input the coefficients ( a=2, b=1, c=-3)

3

2= 1= -3=

4 = to get the 1st solution

= to get the 2nd solution

(x 1)(2x  3)  0
x  1and x   3

2



Factorize P(x)  2x3  5x2  9x 18 completely and determine
its zeros.

Step Action
1 MODE 5 to enter EQN mode

2 4 to choose QUBIC form
Input the coefficients ( a=2, b= 5, c= 9, d= 18)

3

2= - 5= - 9 = 18=

Step Action
4 = to get the 1st solution

= to get the 2nd solution

= to get the 3rd solution

We can easily convert into factorization form

5 Base on the solutions from calculator x  2, x  3, x  3

2

We can easily convert into factorization form
P(x)  (x  2)(x  3)(2x  3)
When P(x)  0, the zeros are  2, 3and 3

2



Solve for x + 2y = 3 and 2x + 3y = 4
Step Action
1 MODE 5 to enter EQN mode

2 1 anX + bnY = cn
Input the coefficients

3 1= 2= 3=

2= 3= 4=

4 To get the solutions
= x = 1
= y= 2

Solve the followings system of linear equation
x–y+z=2
x+y–z=0
–x + y + z = 4

Step Action

1 MODE 5 to enter EQN mode

2 1 anX + bnY + cnZ= dn

Input the coefficients
3

1= - 1 = 1 = 1=

1= 1= - 1 = 0=

- 1= 1= 1 = 4=

Step Action
4 To get the solutions
= x= 1
= y= 2

= z= 3
