HSC Maths Ext2 - Complex Numbers - Finding Square Roots of Complex Numbers

Welcome to my HSC 4 Unit maths: Complex Numbers series. In this video, we see how to find the square roots of complex numbers, which will be useful for solving quadratics with complex coefficients.

This was probably the most helpful video i’ve watched. Easy to understand and straight to the point. Thank you so much.

This is the first video I watched that is related to finding the square root of complex number and I fell so confident and this was so helpful.
"THANK YOU SO MUCH SIR".

[vrindayadav]

I wanted to ask that we had our no. In simple form then why did we took root of that no in step 1

[joshackerman]

Sir, I have my final tomorrow and you just saved my a$$

[OriginalSuschi]

Why don't we look at the Complex solutions xD We started with a complex number anyway lol (although if we'd do this our result of + or - (3+2i) is the solution for both cases (x^2)-9=0 and (x^2)+4=0

[shamsudinabdi]

Thank you sir your video helping me. And you explain clearly

[shaaminbwoy]

Hey man why did you say 4 would not be a real number but -9 would?

[salmonsushi]

Props to the fly for makin it into the video

[gatlatwal]

Please help me calculate this
Given that (√3-i) is a square root of the equation Z^9+16(1+i)z^3+a+ib=0
What is the value of a and b?

[bollywoodpie]

How i square is -1 sir can u explain this

[bluebacon]

is this high school level math or collage level math in the states?
