Rewrite the function by completing the square. f(x)=x^2+14x+8

f(x)=(x+__)^2=__

And solving we got:

And we can reorder the terms we got:

And that would be the equivalent expression for the problem

Step-by-step explanation:

For this case we have the following function given:

And we can complete the square adding the middle of 14 squared and subtracted before like this:

And solving we got:

And we can reorder the terms we got:

And that would be the equivalent expression for the problem

x = ± 6i

step-by-step explanation:

x^2 = -36

take the square root of each side

sqrt(x^2) = sqrt(-36)

we know sqrt(ab) = sqrt(a) sqrt(b)

x = ±sqrt(36) sqrt(-1)

we know that sqrt (-1) = i

x = ± 6i

i got 142 as my answer
