Discriminant D is given by: D=b²-4ac Implication of discriminant is as follows:
D<0 two zeros that are complex conjugate D=0 one real zero of multiplicity 2 D>0 two distinct real zers D= (+ve perfet square) two distinct rational zeros From: 12x^2+10x+5=0 plugging in the equation we get: 10²-4×12×5 =100-240 =-140 thus D<0
Answer is: <span>A two irrational solutions </span>
For this case we have an equation of the form: Where, h0: initial height v0: initial speed a: acceleration Substituting values we have: Rewriting we have: Note: see attached image Answer:
