Answer 2

Answer:

Step-by-step explanation:

Let , p = -2

and q = 4

Then, p+q = -b/a {in ax²+bx+ c}

also, p×q = c/a

We can express these equations in,

p+q = -2+4=2=-b/a and

p.q =-2×4 =-8= c/ a.

If we assume a=1

Then,-b=2

i.e,b=-2

Also,c =-8

Then our required quadratic equation is:

x²-2x²-8=0
