____________________________________________

cubic polynomial 's formula :-

x^3 - ( a + b + y )x^2 + ( ab + by + ya )x - aby

____________________________________________

➪ x^3 - [ 2 + ( -3 ) + 4 ]x^2 + [ 2 * ( -3 ) + ( -3 * 4 ) + 4 * 2 ]x - 2 * ( -3 ) * 4

➪ x^3 - ( 2 - 3 + 4 )x^2 + [ ( -6 ) + ( -12 ) + 8 ]x - ( -24 )

➪ x^3 - ( -3 )x^2 + ( -6 - 12 + 8 )x + 24

➪ x^3 + 3x^2 + ( -10 )x + 24

➪ x^3 + 3x^2 - 10x + 24
