Question

√(x-m)=x-1 E urgeent !!!!

Answer 1

Conditii x≥m; x≥1, ridicat la patrat; x^2-3x+1+m=0, Δ=9-4(m+1), $x_{1}= \frac{3- \sqrt{5-4m} }{2}; x_{2}= \frac{3+ \sqrt{5-4m} }{2}$, daca m>5/4 ⇒Δ<0, ec. nu are solutii, daca m=5/4⇒doua solutii confundate =3/2, m<5/4, 2 radacini ce trebuie sa varifice ,prima radacina indelineste conditiile pentru m∈[1,5/4], a doua pentru m≤5/4.
