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 :)

1.3

step-by-step explanation:

3x2=6   9x+6

bring down the 6 on both sides

6+6=12

12= 9x

divide by 9

12/9 =

1.3 =x
