∙ 11y agoIf you subtract 15 from -6 you get -21. If you worked out the problem on paper, this is what it would look like. -6 - 15 = ? (change the minus to a plus, and change the sign of 15 from positive to negative) -6 + -15 = ? ( now you can add negative 6 plus negative 15 which equals negative 21) -6 + -15 = -21
-20 -(-5) = -15 ie -(-5) = +5 therefore -20 +5 =15 (two double minuses = a positive)
X= 1.567764363, -9.567764363
(x + 1)(x - 15) gives roots of -1 and 15, and a = 14; (x + 5)(x - 3) gives roots of -5 and 3, and a = 2.
x = 15

Negative 15 plus positive 20 equals 20 minus 15, which equals 5.
I think you mean "What does negative 10 minus 5 equal?" If not, please correct me. But, the correct answer would be -15 or negative 15.

Negative 4 minus positive 15 = negative 19

-15 - (-15) = 0
(x + 1)(x - 15) gives roots of -1 and 15, and a = 14; (x + 5)(x - 3) gives roots of -5 and 3, and a = 2.
x = 15
-15 minus -4 is -11.
Well there are quite a few numbers that added together will equal negative 15: here are just a few examples: negative 1 plus negative 14 equals negative 15 (-1 + -14 = -15) negative 2 plus negative 13 equals negative 15 (-2 + -13 = -15) negative 3 plus negative 12 equals negative 15 (-3 + -12 = -15) negative 4 plus negative 11 equals negative 15 (-4 + -11 = -15) negative 5 plus negative 10 equals negative 15 (-5 + -10 = -15) negative 6 plus negative 9 equals negative 15 (-6 + -9 = -15) negative 7 plus negative 8 equals negative 15 (-7 + -8 = -15) negative 30 plus positive 15 equals negative 15 (-30 + 15 = -15) negative 29 plus positive 14 equals negative 15 (-29 + 14 = -15) negative 28 plus positive 13 equals negative 15 (-28 + 13 = -15) and on an on it goes.
