-x2 + 6x + 16 = -(x2 - 6x - 16) = -(x - 8)(x + 2) = -(8 - x)(x + 2)
As a polynomial in standard form, x plus 5x plus 2 is 6x + 2.
(6x + 1)(x + 2)
5x^2 + 6x + 9 + (?) = -x^2 +3x + 3 (?) = -5x^2 -6x - 9 -x^2 +3x + 3 = -6x^2 -3x -6 Ans: -6x squared +3x -6
(x^2 - 6x + 18)(x^2 + 6x + 18)
-x2 + 6x + 16 = -(x2 - 6x - 16) = -(x - 8)(x + 2) = -(8 - x)(x + 2)
As a polynomial in standard form, x plus 5x plus 2 is 6x + 2.
(6x + 1)(x + 2)
5x^2 + 6x + 9 + (?) = -x^2 +3x + 3 (?) = -5x^2 -6x - 9 -x^2 +3x + 3 = -6x^2 -3x -6 Ans: -6x squared +3x -6
x2 + 6x + 8 = (x + 4)(x + 2)
7x + 2 = 6x + 2 if and only x = 0.
(x^2 - 6x + 18)(x^2 + 6x + 18)
x^2+6x+2=9 x^2+6x-7=0 (x+7)(x-1)=0 x=-6,1 for your roots
x2 + 6x + 8 =(x + 2)(x +4)
6x + 2 = 6 6x = 4 x = 2/3
12 + x = 6x + 2; subtract 2 from both sides 10 + x. = 6x;; subtract x from both sides 10 = 5x; divide both sides by 5 2 = x; x = 2
is it 6+6x-2. If it is than it should be 6x+4. Then you can solve for X. Which gives you X=-2/3
