Lösung 2.3:2c
Aus Online Mathematik Brückenkurs 1
We start by completing the square of the left-hand side,
The equation is then
The first term \displaystyle \bigl(y+\tfrac{3}{2}\bigr)^{2} is always greater than or equal to zero because it is a square and \displaystyle \tfrac{7}{4} is a positive number. This means that the left hand side cannot be zero, regardless of how y is chosen. The equation has no solution.
