Question

find the quadratic polynomial, the sum and product of whose zeroes are -8 and 12 respectively. hence find the zeroes.​

Answer 1

Answer:

formula to make quadratic polynomial=

x²-(sum of zeros)x +(product of zeros)

x²-(-8)x+12

x²+8x+12

x²+6x+2x+12

x(x+6)+2(x+6)

(x+2)(x+6)

if x+2=0

x=-2

if x+6=0

x=-6
