Answer:

....5x²+12x+3=0

the equation is of the form ax²+bx+c=0

a=5; b=12; c=3

b²-4ac= 12²-4(5*3)=84

Δ84, √Δ84=2√21>0; 2solutions

(-b-√Δ)/2a =(-12-2√21)/10 = (-6-√21)/5

(-b+√Δ)/2a=(-12+2√21)/10 =(-6+√21)/5

the exact solutions of the equation 5x2+12x+3=05x2+12x+3=0 are:

(-6-√21)/5 and (-6+√21)/5
