Question

Form a Quadratic polynomial whose sum of zeros is -4 and product of zeros is 8.

a) y²+4y+1
b) y²+4y+8
c) 4y²-y+8
d) 4y²+y+8​

Answer 1

Answer:

B) y2+ 4y+8=0

..........

Answer 2

Answer:

Let say a & b are zeroes then Quadratic polynomial would be (y - a) (y - b)

Simplify (y - a)(y - b)

sum of zeros is -4 and product of zeros is 8. hence a + b = - 4 and ab = 8

substitute these values in simplified expression
