Answer:

a = -1, b = 2

Step-by-step explanation:

x2+ax+b= x(x-2) + x(a+2) -2(a+2)

=(x - 2) (x+a+2)

comparing constant terms on both sides we get

b= -2(a+2)

= - 2a - 4

substituting the value of b in a+b = 1

a - 2a -4 = 1

-a - 4 = 1

-a =5

a = -5 , b = 1 - a

b = 1 + 5 = 6

belieberanonymus: jeez ur answer doesnt match

belieberanonymus: ohh sry its correct
