Question

दिलेलं वर्गसमीकरण अवयव पद्धतीने सोडवा: 5m² = 22m + 15

Answer 1

$\mathfrak{ \huge{Solution \colon}}$

5m² = 22m + 15

5m² - 22m - 15 = 0

Splitting the middle term we get

5m² - 25m + 3m - 15 = 0

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

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

Therefore ,

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

m = 5 or 5m = -3

m = 5 or m = -3/5
