Hope it helps you.

Answer 2

Answer:

$5 {m}^{2} - 22m - 15 = 0 \\ \\ \\ = 5 {m}^{2} - 25m + 3m - 15 \\ \\ \\ = 5m(m - 5) + 3(m - 5) \\ \\ \\ \\( 5m + 3)(m - 5) = 0 \\ \\ \\ m = \frac{ - 3}{5} \\ \\ \\ m = 5 \\ \\ \\ \\ hence \: the \: zeroes \: of \: this \: polynomial \\ \: are \: \: \\ \\ \\ \frac{ - 3}{5} and5$
