Which of the following represents the zeros pf f(x)=x3-2x2-6x+12

When x = ±√3, -2, then the factors are (x - √3)(x + √3)(x + 2) = 0.

(x - √3)(x + √3)(x + 2) = 0

(x² - 3)(x + 2) = 0

x³ + 2x² - 3x - 6 = 0 (Second choice)

an

y = 6x -3y -12

y +3y +12 = 6x

=> . x = { 2y / 3 +2 } this is equation of line in terms of x

=> . if line meets the x-axis the co-ordinates of meeting point would be ( x , 0 )

=> . x = 2 ( 0 ) / 3 + 2

=> . x = 2

so, the point is ( 2 , 0 )
