jika
x² + 5x + 6 = 0

maka berapa nilai dari x

Answer 1

Verified answer

X² + 5x + 6 = 0
x² + 2x + 3x + 6 = 0
x(x + 2) + 3(x + 2) = 0
(x + 2)(x + 3) = 0

x = -2 dan x = -3

semoga membantu

Answer 2

X² + 5x + 6 = 0

• cari 2 bilangan yg bila dikalikan = 6
dan bila dijumlahkan = 5
yaitu 2 dan 3

x² + 5x + 6 = 0
x² + 2x + 3x + 6 = 0
x(x + 2) + 3(x + 2) = 0
(x + 2)(x + 3) = 0
x + 2 = 0 ---> x = -2
atau
x + 3 = 0 ---> x = -3
