What is the cubic equation?
The polynomial having a degree of three and the maximum power of the variable is three is called the cubic equation.
The solution of the cubic equation will be calculated as follows-
( 2x - 7) ( x² -4x + 4 ) = 0
(2x - 7 ) ( x² - 2x -2x + 4 ) = 0
(2x - 7 ) [ x ( x - 2) - 2 ( x - 2 )]= 0
( 2x - 7 ) ( x - 2 ) ( x - 2 ) = 0
x = 0 and x = 2/7
Therefore the value of x will be equal to x = 2 and x = 7/2.
