Form the union for the following sets m={} n={6,7,8,9,10}

Levart [38]

Answer:

$M\cup N$ ={6,7,8,9,10}.

Step-by-step explanation:

We have an empty set: M={} and the set N={6,7,8,9,10}.

The union of these two sets are elements in M or N or both.

Since the M is a null set, $M\cup N=N$

Therefore: $M\cup N$ ={6,7,8,9,10}.

The union for the given sets is {6,7,8,9,10}.

Step-by-step explanation:

$(8 {x}^{2} - 5x + 1) - (3 {x}^{2} - x + 4) \\ = 8 {x}^{2} - 5x + 1 - 3{x}^{2} + x - 4 \\ = 5 {x}^{2} - 4x - 3$
