Answer:

Two values of x that are :

x=-\sqrt{7}-1

x=\sqrt{7}-1

Step-by-step explanation:

Given= x^2+2x-6=0

To find = Two values of x

Solution :

x^2+2x-6=0

Adding and subtracting 1 in the equation :

x^2+2x+1-1-6=0

(x^2+2\times x\times 1+1^2)-1-6=0

(x+1)^2-7=0

(x+1)^2=7

(x+1)=\pm \sqrt{7}

Two values of x that are :

x=-\sqrt{7}-1

x=\sqrt{7}-1

If you line them up in that order 247 you'll have to borrow. Your answer would be -291
                                                  -538

The only way to not get -291 is to flip the two numbers.
