5 m² = 22 m+15​

Answer 1

Answer:

m = -3/5  or m = 5

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

So,

5m+3 = 0 or  m-5 =0

m = -3/5  or m = 5

Answer 2

Answer:

$5 {m}^{2} - 22m - 15 = 0$

$5 {m}^{2} - 25m + 3m - 15 = 0$

5m (m-5)+3 (m-5)

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

m-5=0 or 5m+3=0

$m = 5 \: or \: m = \frac{ - 3}{5}$
