Answer 2

The value of x will be equal to x = 2 and x = 7/2.

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.
