Question

A={x/x²-5x+6=0}
B={2.4}
C={4.5}
(A-B)×(B-C)​

Answer 1

Answer:

(A-B)×(B-C} = {(3,2)}

Step-by-step explanation:

A = {x/x²-5x+6=0}

= {x/x²+(-2-3)x+(-2)(-3)=0}

= {2,3}

B = {2,4},

C = {4,5}

Now,

i) A-B = {2,3}-{2,4}= {3}

ii) B-C ={2,4}-{4,5} = {2}

iii) (A-B)×(B-C}={3}×{2}

= {(3,2)}

Therefore,

(A-B)×(B-C} = {(3,2)}
