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.

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
