Quadratic equations and complex numbers
Did you know?
WebOne of the first major results concerning complex numbers, and which conclusively demonstrated their usefulness, was proved by Gauss in 1799. From the quadratic formula (1) we know that all quadratic equations can be solved using complex numbers, but what Gauss was the first to prove was the much more general result: WebA quadratic equation is of the form ax2 + bx + c = 0 where a, b and c are real number values with a not equal to zero. Consider this example: Find the roots: x2 + 4x + 5 = 0. This …

WebFirst of all, real part of any complex number (a+ib) is represented as Re (a + ib) = a and imaginary part of (a +ib) is represented as Im (a+ib) = b. Also, when two complex numbers are equal, their corresponding real parts and imaginary parts must be equal. Therefore, if a + ib = c + id, then Re (a+ib) = Re (c+id) and Im (a+ib) = Im (c+id) sephora own brandWebHaving this new knowledge allows us to explore one more possible outcome when we solve quadratic equations.
