    k(x^2+6x-7) = 0 where k is a non-zero value.

    same solution as x^2 +6x -7 =0

    since you can multiply both sides of the equation by

    an integer constant k and keep the same solution.

    any equation such that

    k ( x^2 +6x -7) = 0

    where k is a non-zero integer will have the same solutions

    so

    k = 2

    2x^2 +12x -14 =0

    k= -2

    -2x^2 -12x +14 =0

    k = 50

    50x^2 +300x - 350 =0

    so pick any non-zero integer k and multiply the

    original by it. Then, it will have the same

    set of solutions.

  • (x+7)(x-1)=0

    x = -7, x = 1

    (x + 7)(x - 1) = 0

    x² + 6x - 7 = 0 has the same solutions as -x² - 6x + 7 = 0 (as one example).

    But, this question is phrased like a multiple choice question, so can you please include the choices?

    How about the equations 3(x2+6x-7) = 0, or e^x * (x2+6x-7) = 0 or |x-3| - 4 = 0.

    x2+6x-7=0

    8x = 7

    other equations with same solution

    16x = 14

    80x = 70

    800x = 700

    (x+7)(x-1) = 0

    x = -7 or 1
