Code:

Set Calculator to equation mode: MODE>5>4 for cubic equation

Mode 4 because our polynomial is a 3rd degree equation..

Input the equation coefficients a,b,c:

1 = -7 = 1 4 = -8 = =

And you will get the answer..

3. Which of the following is a possible root of the polynomial:

A. 3

B. 0

C. -2

D. 4

Code:

NOTE: A root is any value that, when substituted to the variable(ie x), will satisfy the equation.(In our equation 0=0 )

Set the calculator to computation mode: MODE>1

Input ONLY the left side of the equation.

Trial and error, Use the CALCU function..

Pag nagtanong ang calculator X? iinput ang mga choices..

X? 3 =

output is 240..

repeat the step until you get an output of 0..

And you will get the answer..

4. Find the value of x and y in the following equations:
