Question

if alpha and beta are the zeros of the quadratic polynomial 2-3x-xsquare ,then find alpha + beta​

Answer 1

Answer:

ans is 3

Step-by-step explanation:

given eq is -x²-3x+2

now multiple the above eq with - then it becomes

x²-3x+2

now compare the eq with ax²+bx+c

then a= 1 b= -3 c=2

the formula for sum of products (alpha+beta )

= -b/ a

alpha + beta = -(-3)/1

= 3

therefore alpha+beta =3
