Question

solve the quadratic equation by factoriztion method 5m2 - 22m - 15= 0​

Answer 1

Step-by-step explanation:

here we use splitting the middle term to solve this method

Answer 2

Answer:

$\mathfrak{ \huge{ \green{question : }}}$

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

$\mathfrak{ \huge{ \green{solution : }}}$

$5 {m}^{2} - 22m - 15 = 0 \\ \\ { \underline{splitting \: the \: middle \: term : }} \\ 5 {m }^{2} - 15m + 3m - 15 = 0 \\ 5m( m - 3) + 3(m - 3) = 0 \\ (m - 3) (5m + 3) = 0 \\ \\ m - 3 = 0 \: { \boxed{or}} \: 5m + 3 = 0 \\ m = - 3 \: { \boxed{or}} \: m \: = \frac{ - 3}{5}$

$\mathfrak{ \huge{ \blue{hence}}} \\ the \: value \: ofm \: is \: - 3 \: or \: \frac{ - 3}{5} .$
