Which three steps are correct when solving this quadratic equation by completing the square? X^2-10x=39

Step-by-step explanation:

Any answer that involes,

Step 1: Complete the Square

Step 2: Turn the left side into a binomial

Step 3: Solve for x.

OR

X=-3 or X=13

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
