Question

Sa se descompuna in factori de forma mx+n, m,n apartine multimii nr. complexe:
x^2-x+7.
am scris a=1,b=-1,c=7 am aflat delta,radacinile x1,x2 si nu stiu cum sa scriu pt mx+n

Answer 1

[tex]ax^2+bx+c=a(a-x_1)(x-x_2)\\ x^2-x+7=0\\ \triangle=1-28=-27\\ x_{1/2}= \frac{1\pm3\sqrt{3}i}{2} \\ x^2-x+7=(x-\frac{1+3\sqrt{3}i}{2})(x-\frac{1-3\sqrt{3}i}{2})[/tex]
