Question

PLZ SOLVE ASAP.........

Answer 1

yes because

2*m^2=5*m
m^2/m=5/2
so the ans is m=5/2
it is the root of the given ques

Answer 2

Hope you like my process
=======================
Process (1)
==========
=> 2m² - 5m = 0

=> m(2m -5) = 0

So ,

either : m = 0

or : 2m - 5 = 0

=> m = 5/2

_________________________
Process (2)
==========
=> 2m² - 5m = 0

=> 2m² = 5m

Dividing both sides by 2m
----------------------------------------
=> m = 5/2
_________________________
Process (3)
==========
We know , Sreedhar acharya's Formula
-----------------------------------------------------------
$\bf \: \: for \: \: quadratic \: \: equation \: \\ \\ \: \: \: \: \: \: \: \: \bf \blue{a {x}^{2} + bx + c = 0}\\ \\ = > x = \: \frac{ - b + - \sqrt{ {b}^{2} - 4ac} }{2a} \\ \\ if \: \: \: c = 0.... \\ \\ = > x = \frac{ - b + - b}{2a} = \bf \: 0 \: \: \: or \: \: - \frac{b}{a}$

Thus ..here c=0

so ..

either
$= > \bf \: m = - \frac{ - 5}{2} = \frac{5}{2}$
or

=> m=0

________________________
THUS , 5/2 and 0 are the roots of the equation

=> 2m²-5m=0
