X^2-16=-13
Add 16 to both sides
x^2 = 3 Take the square root of both sides....remember, we need to take both roots - positive and negative
x = ±√(3)
And that's it.......
$$X^2-16=-13 Add 16 X^2=3 Square root it and you estimate$$
first you need to subtract 16, or add negitive 16 to each side
then, just take the square root of -26, and you have x!
