Put x = 3

2x - 5

= 2(3) - 5

= 6 - 5

= 1

Put x = 2

2x - 5

= 2(2) - 5

= 4 - 5

= -1

3 and 2 are not zeros of 2x -5.

Lemma is used for proving any statement

Meghna Thapar 6 years ago

In mathematics, informal logic and argument mapping, a lemma (plural lemmas or lemmata) is a generally minor, proven proposition which is used as a stepping stone to a larger result. For that reason, it is also known as a "helping theorem" or an "auxiliary theorem".
