Place the following steps in order to complete the square and solve the quadratic equation, x^2+7=0

X^2+7=0

this can be written as:

x^2+0x+7=0

To solve using completer square we proceed as follows:

x^2+0x=-7

but

c = (b/2a) ^2

c = (0/2*1) ^2=0

hence

x^2+0x+0=-7+0

this will be simplified as:

x^2=-7

getting the square root of both sides gives us:

sqrt (x^2) = sqrt (-7)

x=+/-√-7

but √-1=i

hence our answer will be:

x=+/-7i
