5m² - 22m - 15 = 0

Answer 1

Answer:

Step-by-step explanation:

5m²-22m-15=0

5m²-25m+3m-15=0

5m(m-5)+3(m-5)=0

(5m+3)(m-5)=0

Answer 2

$\textbf{5m}^{ \textbf{2}} \textbf{ - 22m - 15 = 0} \\ \\ \rightarrow \: \textsf{5m}^{ \textsf{2}} \textsf{ - 22m - 15 = 0} \\ \\ \rightarrow \: \textsf{5m}^{ \textsf{2}} \textsf{ - (25 - 3)m - 15 = 0} \\ \\ \rightarrow \textsf{5m}^{ \textsf{2}} \textsf{ - 25m + 3m - 15 = 0} \\ \\ \rightarrow \textsf{5m(m - 5) + 3(m - 5) = 0} \\ \\ \rightarrow \textsf{(5m + 3)(m - 5) = 0} \\ \\ \\ \implies \text{5m + 3 = 0} \\ \\ \rightarrow \text{5m = -3} \\ \\ \rightarrow \text{m} = \frac{-3}{5} \\ \\ \\ \implies \text{m - 5 = 0} \\ \\ \rightarrow \: \text{m = 5}$

$\boxed{ \textsf{m = } \frac{-3}{5},5}$

$\textbf{Verification}$

$\implies \textsf{(5m + 3)(m - 5) Multiplying...}$

$\rightarrow \text{5m ^{2} - 25m + 3m -15}$

$\rightarrow \text{5m ^{2} - 22m -15}$

$\boxed{ \textsf{Hence verified}}$
