Question

sa se scrie ecuatia care are drept solutiile 5 si 1/2​

Answer 1

Răspuns:

Explicație pas cu pas:

$S=x_1+x_2=5+\dfrac{1}{2}=\dfrac{11}{2}\\P=x_1\cdot x_2=5\cdot\dfrac{1}{2}=\dfrac{5}{2}\\\texttt{Ecuatia este de forma:}\\x^2-Sx+P=0\\x^2-\dfrac{11}{2}x+\dfrac{5}{2}=0|\cdot 2\\\boxed{2x^2-11x+5=0}$
