It is impossible but if it were x squared plus 2x minus 15 the equation would be (x+5) (x-3) with x being equal to either -5 or 3. If the original problem was x squared minus 2x minus 15 the equation would be (x-5)(x+3) and x would be equal to either 5 or -3

Do two plus signs make a minus?

In addition and subtraction, if the plus sign is larger than the minus sign, then it's a plus. For example: +10 minus -20 = -10 If the plus sign is smaller than the minus sign, the answer will be a minus. For example: -10 minus + 20 = -10 In multiplication, if you have 2 plus signs, the answer will be a plus sign. If you have 2 minus signs, the answer will be a plus sign then, too. But if you have a plus and a minus sign, then the answer will be a minus. For example: +5 x + 2 = +10 -5 x - 2 = +10 -5 x +2 = -10
