1.If the expressions x2−11x+ax^2 - 11x + ax2−11x+a and x2−14x+2ax^2 - 14x + 2ax2−14x+2a must have a common factor and a≠0a \neq 0a=0, then the common factor isa.(x−3)(x - 3)(x−3)b.(x−6)(x - 6)(x−6)c.(x−8)(x - 8)(x−8)d.None of theseLogin to continueOnly logged in users canattempt or see the solution.
