Question

If (x-3) and (x-1/3) are factors of ax^2 +5x+b, prove that a=b

Answer 1

Answer:

Step-by-step explanation:

x-3=0

x=3

put it in the eq.

9a+15+b=0

9a+b=-15---1

x-1/3=0

x=1/3

a/9+5/3+b=0

(a+15+9b)/9=0

a+15+9b=0

a+9b=-15

subtracting 1 and 2

9a+b=-15

a+9b=-15

(-)  (-)   (+)

________

8a - 8b =0

8(a-b)=0

a-b=0

a=b

Answer 2
