put all terms on one side (the left one for example), and use the formula involving the discriminant \(\Delta\): the solutions are given by the formula \(-\frac{-b\pm\sqrt\Delta}{2a}\) (if the equation is \(ax^2+bx+c=0\))

Whats the discriminant?
reemii
  • reemii
it's the quantity noted \(\Delta\) , the value is \(b^2-4ac\).

the correct fraction is \(\frac{-b\pm\sqrt{\Delta}}{2a}\) (i put a minus sign in the first message that shouldn't be there)

Im gettting a triangle under that √, id that right?
reemii
  • reemii
yes. what is your \(\Delta\) ? if it's correct then you will most likely find the two solutions.

i don't know really what you did.. write \(x^2+3=-4x\) as \(x^2+4x+3=0\) and recognize the values of \(a,b,c\). Here \(a=1,b=4,c=3\).
