Answer 2

Answer:

hello your answer is:

Step-by-step explanation:

m2 + 8m = -16

m2 + 8m + 16 = 0

we have to find 2 such numbers whose sum is +8 and product is +16 such no. are +4 and +4

m2 + 4m + 4m + 16 = 0

m ( m + 4 ) +4( m + 4 ) = 0

( m+4 ) ( m+4 ) = 0

m = -4 , -4

m = -4

Alternative method:

m2 + 8m + 16 = 0

(m + 4)∧ 2 = 0                         { Since m2 + 8m + 16  is square of m + 4 }

m + 4 = 0                                { Squarerooting both sides }

m = 4

Hope that helps!!!
