Question

the quadratic polynomial sum of whose zero is -2 and product is 8​

Answer 1

Step-by-step explanation:

sum of zeroes = -2

product of zeroes = 8

we know that sum of zeroes= alpha + beta which is nothing but -b÷a

and the product of zeroes = alpha × beta which is also nothing but c÷a

Alpha + beta = -b/a = - ( -2 ) = 2

Alpha × beta = c/a = 8

Therefore, a=1 , b =2 and c = 8

quadratic equation :

x*+2x+8=0
