Question

in the following state whether A=B or not? A={2,3} B={X:X is solution of x^2+5x+6=0}
​

Answer 1

Step-by-step explanation:

A={2,3}

B={X:X is solution of x^2+5x+6=0}

x^2+5x+6=0

x²+3x+2x+6

x(x+3)+2(x+3)=0

(x+3)(x+2)=0

(x+3)=0 or (x+2)=0

x=-3 or x=-2

A is not equal to B.

because their elements are not same.
