Question

Is set C = (x : 26-0) and E - {t: r is an integral positive root of the equation .' – 2x- 15 - 0) are equal?
A.Yes
B. No​

Answer 1

Answer:

ANSWER

A={0}

B={0} as no such element s.t x>15 and x<5

C={5} x:x−5=0

D={−5,5} x2−25⟹x=−5,5

E={−3,5} 

 Roots of the equation x2−2x−15=0

⟹(x−5)(x+3)=0

⟹x=−3,5

So the pair of equal sets are A and B.
