Answer:
sum of zeros=2+6=8
product of zeros=2×6=12
we know that each polynomial is of the form
k(x²-(sum of zeros)x+product of zeros)
k(x²-8x+12)
let k be 1
1(x²-8x+12)
x²-8x+12 is the required polynomial
we know that sum of zero= -b/a
-8=-8/1
-8=-8
therefore
sum of zeros=-cofficiant of x/cofficiant of x²
we also know that
product of zero=c/a
12=12/1
12=12
therefore
product of zero=constant term/cofficiant of x²
hope it helps you
