Question

Check whether the value given in the brackets is the root of the given equation or not: 4m -3=-5 (m=-3)

Answer 1

Answer:

m=-3 is not the root

Step-by-step explanation:

4m-3=-5

if m=-3

LHS=4m-3

=4×-3-3

=-12-3

=-15

RHS=-5

LHS≠RHS

Answer 2

$\: \: \: \: \: \: \: \: \: \: \: \: \: \: \sf{4m - 3 = - 5}$

$\: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \sf{4m = - 5 + 3}$

$\: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \sf{4m = - 2}$

$\: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \sf{m = - \frac{2}{4}}$

$\: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \sf{m = - \frac{1}{2} }$

-3 is not a root while -½ is a root
