Bantu jawab pakai langkah langkah caranya ya​

JAWABAN :

a. x² + 6x + 8 = 0

(x+4)(x+2)

x1 = -4

x2 = 2

b. x² + 3x – 10 = 0

(x+5)(x-2)

x1 = -5

x2 = 2

c. x² – 2x – 15 = 0

(x+3)(x-5)

x1 = -3

x2 = 5

d. x² – 36 = 0

(x+6)(x-6)

x1 = -6

x2 = 6

e. 2x² + 13x + 15 = 0

½(2x+10)(2x+3)

x1 = -5

x2 = -3/2

Maaf kalo salah

Follow aku yaaa

JANGAN ASAL REPORT 🙂

Jawaban:

soal a

(x+2)(x+4) = 0

x = -2 dan x = -4

soal b

(x-2)(x+5) = 0

x = 2 dan x = -5

soal c

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

x = -3 dan x = 5

soal d

(x+6)(x-6) = 0

x = -6 dan x = 6

soal e

(2x+3)(x+5) = 0

x = -3/2 dan x = -5
