Solving Radical Equations part 2 of 2

[@lunargachagirl]

Helped loads! Even after 12 years this video still has such power! Thanks so much!! =)

For the first example 2(-11)+3 = -19 not 18 also I would like to ask -11-8=-19 as well so shouldn't sqrt(-19) - sqrt(-19) = 0 ??

[@bbw1979]

The number under a square root MUST be positive. Since -19 is not, then -11 is not a solution to the equation.

@@bbw1979 actually apparently you can simplify √-19 into i√19 and i√19- i√19=0

Thank you so much! I just spent the last hour reading, and trying the examples in the book. And finding un-useful info on both google and youtube. Yours was hands down the best! =) I like math again. Thanks again.

i know right !!

In the first question, I arrived at square root of -19 minus square foot of -19
