Question

Faktor dari 6xkuadrat - 6x -7 adalah

Answer 1

6x² - 6x - 7 = 0
x₁,₂ = (-b +- √(b² - 4ac))/2a
= (6 +- √(36 - 4(6)(-7))/12
= (6 +- √(36 + 168))/12
= (6 +- √204)/12
maka:
x₁ = (6 + √204)/12 dan x₂ = (6 - √204)/12

Answer 2

x₁,₂ = (-b +- √(b² - 4ac))/2a
= (6 +- √(36 - 4(6)(-7))/12
= (6 +- √(36 + 168))/12
= (6 +- √204)/12
maka:
x₁ = (6 + √204)/12 dan x₂ = (6 - √204)/12
