Directions for solving radicals that have a negative value. This involves simplifying the negative radical. Sounds difficult,but after working a few problems you will find they aren't that hard.

Video Guide

0:24 5i times the square root of -64 You will solve this problem by simplifying the square root of 64. Next you convert the square root of -1 into "i" move the coefficient down and multiply.

4:48 Simplify square root of -81 + 3i -2 Again you simplify the square root, bring down the coefficient, and add like terms. Remember these problems should be written in the a + bi form.

2:43 This next problem involves a fractional square root with a negative number.

3:00 This is another problem containing a fraction and a negative number.

4:04 The last problem simplifies the negative square root of 9 times the negative square root of 36
