To make things simple, a general formula can be derived such that for a quadratic equation of the form ax²+bx+c=0 the solutions are x=(-b ± sqrt(b^2-4ac))/2a. The quadratic formula comes in handy, all you need to do is to plug in the coefficients and the constants (a,b and c). Tính căn (x^2-4x+4)=5. \ (\sqrt {x^2-4x+4}=5\) Theo dõi Vi phạm.
