Question

Set"A" containing the elements that are the solution of X+Y=1 and X-Y=5 ,set B contains elements, which are roots of x square +5x+6. Draw AUB,An (interestion)B and A-B......... according to 10th class

Answer 1

Answer:

Step-by-step explanation:

X+Y=1

X-Y=5

2X =6

X =3

Y= -2

SetA {3,-2}

X^2 +5X +6 = 0

X^2 +3X +2X +6 =0

(X+3)(X+2)=0

X = -3 , -2

SetB = {-3,-2}

AUB = {3,-3,-2}
