Which equation has x = –6 as the solution?

**Answer:**

Other examples are possible. Since x=−6 is a solution to equation, we can set up factored equation with x=−6 as a zero.

Few examples:

(x+1)(x+6)=0

(x+6)(3−2x+7x2)=0

(cosx+17x2)(x5+6)(x+6)=0

Only thing that matter is to write the equation in factored form and (x+6) must be one of the factors.
