Question

(5) (m + 2) (m - 5) = 0​

Answer 1

Answer:

Step-by-step explanation:

Answer 2

Answer:

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

(5)(m2+3m-5m-15)=0

(5)(m2-2m-15)=0

5m2-10m-75=0

5m2-10m=75

Now,

3rd term={1/2×coefficient of m}2

={1/2×(-10)}2

={-5}2

=25

•5m2-10m+25=75+25

(√5 m - 5)2=100

√5 m - 5= +/-10........Taking Square Roots On Both Sides

m=+/-10+5 // √5
