If y = x² - 6x + 11 is written in the form y = a ( x - h )² + k, find the value of ( a + h + k).

6

Step-by-step explanation:

y = x² - 6x + 11

Complete the square.

y = x² - 6x + 9 + 2

y = (x - 3)² + 2

a = 1, h = 3, k = 2

a + h + k = 6

f(x) = x^3 -2x^2 -3x

x( x^2 -2x-3)

x( x^2 +x -3x -3)

x( x(x+1) -3(x+1))

x( x-3)( x+1)

so zeroes are 0, 3,-1

its (2) option

yes the total will be same because in both of them the expression.is rearranged but their sign remains the same hence it hss just been shuffled
