x2 + 6x = 16=> x2 + 6x - 16 = 0=> x2 + 8x -2x - 16 = 0=> (x+8)(x-2) = 0=> x = -8 or x = 2So, the solutions of the quadratic equation x2 + 6x = 16 are -8 and 2.
Im assuming the "6x2" is supposed to be 6x squared. The factored form would be (2x+1) (3x-8)
x2 + 6x = 16x2 + 6x - 16 = 0(x + 8)(x - 2) = 0x + 8 = 0 or x - 2 = 0x = -8 or x = 2Since it is given that x > 0, then x = -8 is not a solution of the equation. Thus, the only solution is x = 2.
x2+7x-18 = (x+9)(x-2) when factored
8
If you mean: x2+6x+8 then it is (x+4)(x+2) when factored
x2 + 6x - 2 can not be factored
If you mean: 8x2-56x-64 which becomes x2-7x-8 and is (x-8)(x+1) when factored
x2 + 6x - 5 is a quadratic expression that can not be factored.
x2+6x-7 = (x+7)(x-1) when factored
x2-6x can be factored into x(x-6). Simply factor out the "x" from both factors.
x2 + 6x + 5 can be factored into (x+1) (x+5)
x2-6x-27 = (x+3)(x-9) when factored
(X + 2)(X + 4) Factored
-4
-x2 + 6x + 16 = -(x2 - 6x - 16) = -(x - 8)(x + 2) = -(8 - x)(x + 2)
6x5(x2 - 6x + 3)
