## kearsten one year ago medal and fan solve for x x^2=-9/4

1. lfreeman1285

because we're trying to get x all by itself, we need to square root both sides. $\sqrt{x}=\sqrt{-9/4}$ This can be simplified to$\sqrt{-1 * 3 *3}\div \sqrt{4}$ The square root of 4 can be easily simplified to 2, and the pair of threes can be taken out from under the square root. Now you have $3\sqrt{-1}\div2$ There's a variable for the square root of negative one, known as i. We use i because negative numbers aren't able to be square rooted. Therefore, your answer is 3i/2

Sorry if that's a little confusing, I'd be happy to clarify anything for you!
