Matematika x2+6x+8=0 kuadrat sempurna ​

x2+6x+8=0 kuadrat sempurna ​

Jawaban :

HP : {-2,-4}

Penjelasan dengan langkah-langkah :

x² + 6x + 8 = 0

x² + 6x = -8

x² + 6x + (6/2)² = -8 + (6/2)²

(x + 6/2)² = -8 + 36/4

(x + 6/2)² = -32/4 + 36/4

(x + 6/2)² = 4/4

(x + 6/2) = √4/4

(x + 6/2) = ±2/2

x1 + 6/2 = 2/2

x1 = -2

x2 + 6/2 = -2/2

x = -4

HP : {-2,-4}

Jawaban:
