Question

factorise : m2 + 3m +9/4

​

Answer 1

Answer:

m= - 3/2

Step-by-step explanation:

Given

m^2+ 3 m + 9/4=0

here we have to take LCM

Then the equation changes to

4 m^2 +12m +9 =0

Factors of 4×9=36=1×36

=2×18

=3×12

=4×9

=6×6

The above equation satisfies 6×6

4 {m}^{2} + 6m + 6m + 9 = 04m

2

+6m+6m+9=0

2m(2m + 3) + 3(2m + 3) = 02m(2m+3)+3(2m+3)=0

(2m + 3)(2m + 3) = 0(2m+3)(2m+3)=0

So

m= -3/2, m=-3/2
