Which of the binomials below is a factor of this trinomial? 4x2 - 7x - 15

For a polynomial of the form ax2+bx+cax2+bx+c, rewrite the middle term as a sum of two terms whose product is a⋅c=4⋅−15=−60a⋅c=4⋅-15=-60 and whose sum is b=7b=7.Tap for more steps...4x2−5x+12x−154x2-5x+12x-15Factor out the greatest common factor from each group.Tap for more steps...x(4x−5)+3(4x−5)x(4x-5)+3(4x-5)Factor the polynomial by factoring out the greatest common factor, 4x−54x-5.(4x−5)(x=3)

-14x or 14x that's what I think because you add the X to the number you Subtract,Add,Multiplie,or Divide it does not matter and it will either be a negative or positive.
