Question

Cara melengkapi dengan kuadrat sempurna m² - 4m= 5 adalah?

Answer 1

M² -4m +(4/2x2) = 5 + (4/2x2)
m² - 4m + 4 = 5 + 4
(m - 2)² = 9
m- 2 =√9
m-2 =+ 3
m = 2 + 3

m1 = 2 + 3 = 5
m2 = 2- 3 = -1

Answer 2

Melengkapi dengan kuadrat sempurna m² - 4m = 5² ....?
Jawab :
m² -4m + ( 4/2x2 ) = 5 + ( 4/2x2 )
m² - 4m + 4 = 5 + 4
(m - 2)² = 9
m- 2 = √9
m-2 = + 3
m = 2 + 3

m1 = 2 + 3 = 5
m2 = 2 - 3 = -1
