iam completely lost

anonymous · Answer

well do you know what exact solutions are?

anonymous · Answer

solutions to the equation I think

anonymous · Answer

well sorta (want me to explain?)

anonymous · Answer

yeah please

anonymous · Answer

As used in physics, the term "exact" generally refers to a solution that captures the entire physics and mathematics of a problem as opposed to one that is approximate, perturbative, etc. Exact solutions therefore need not be closed-form.

hey hold on ill be right back im bout to change my picture i look old in this one

anonymous · Answer

x = the quantity of negative 5 plus or minus the square root of 3 all over 2
 x= the quantity of 5 plus or minus the square root of 3 all over 2
x = the quantity of negative 5 plus or minus the square root of 53 all over 2
x = the quantity of 5 plus or minus the square root of 53 all over 2

anonymous · Answer

x=$$x={\frac{ 5 \pm \sqrt(53) }{ 2 }}$$

anonymous · Answer

howd u get that

anonymous · Answer

if equation is $$ax^2+bx+c=0$$ then solutions of it iare $$\frac{ -b \pm \sqrt(b^2-4ac) }{ 2a }$$

anonymous · Answer

oh ok I kinda get it now
