In order to figure out this answer you need to multiply the number outside the parentheses "-3" by the terms inside the parentheses "4x" and "-1". -3*4x is -12x and -3*-1 is 3, so the answer is -12x+3, unless your teacher prefers that you put the negative term second, in which case it would be 3-12x
