Model : CASIO fx-991MS, CASIO fx-570MS, CASIO fx-100MS
A two degree equation contains a single variable with maximum power two.it has two roots.It is called quadratic equation. ax2+bx+c=0 is a quadratic equation where x is the variable and a,b,c are constants.This type of equation is solved by a process known as middle term method. But often it's not possible to have the factor. Equation mode of calculator lets you to solve such equations very easily and quickly.
Example: Solve the equation 2x2-3x-1=0.(Ans: 1.78, -0.28)
Solution:
(Mode initialization)
MODE >> MODE >> MODE >> 1(EQN) >> Right of reply button >> 2(Degree)
(Input coefficients)
2(a) >> = >> - >> 3(b,note b is not 3,it's -3) >> = >> - >> 1(c) >> = (x1=1.78) >> = (x2=-0.28)
(After solving equation return to COMP mode,Important)
MODE >> 1
