Question

Factorise 2m^2+m-45
Correct ans pls........

Answer 1

Answer:

2m²+m-45=0

2m²+(10-9)m-45=0

2m²+10m-9m-45=0

2m(m+5)-9(m+5)=0

(m+5)(2m+5)=0

m=-5;m=-5/2

Answer 2

Answer:

m= 9/2 and m=-5

Step-by-step explanation:

2m^2+m-45=0

2m^2+10m-9m-45=0

2m(m+5)-9(m+5)=0

(2m-9)(m+5)=0

m=9/2 , m= -5
