Dear Sir/Madam
My age is 16, and my name is Richard. My question relates to the topic complex numbers & the quadratic formula. I would like to know how to solve quadratic equations in which the discriminant is less than 0 (i.e. we get two complex solutions to the quadratic) 3x^2+2x+5 = 0 and how mathematicians like euler contributed to this field. If it would be possible I would also like to know how this type of quadratic equations can be graphed? Thank you very much for your help and time
Your sincerely
Hi Richard
Euler was the first mathematician to use the letter i to denote this complex number. You can find a historical note on the symbol i at Earliest Uses of Various Mathematical Symbols
