Which equation has the same solutions as x² + 6x - 7 = 0?

(x+3)²=16

Step-by-step explanation:

I'm gonna solve this equation by completing the square

 x²+6x-7 = 0 by Completing The Square

 Add  7  to both side of the equation :  

  x²+6x = 7

Now you take the coefficient of  x , which is  6 , divide it by two = 3 , and finally square it giving 9  

Add 9 to both sides of the equation :

x²+6x+9=7+9

(x+3)x(x+3)=(x+3)²

7+9=16

| (x+3)²=16 |

Now you square root both sides to get x+3=±4

x+3=+4 or x+3=-4

x+3=+4= -7

x+3=-4= 1

x= -7

x= 1

Hope this helps! Have an amazing day :)

i think is 3 and 6. this took me 10 min to think.hope to and hope that my answer is brainliest.(follow me )

i belive those are the ones that are under 90 degreese.
