Question

sa se rezolve ecuatile de gradul al doilea 6x la puterea2-7x+1=0

Answer 1

6x^2-7x+1=0

d-delta 

d=(-7)^2-4*1*6=49-24=25=5^2
x1=(-b+$\sqrt{d}$)/2=(7+5)/2=6
x2=(7-5)/2=2/2=1

Answer 2

6x²-7x+1=0

x=-(-7)+-√(-7)²-4*6*1/2*6

x=7+-√49-24/12

x=7+-√25/12

x=7+-5/12


x=7+5/12
x=7-5/12

x=1
x=1/6

deci x₁=1/6 si x₂=1
