Step-by-step explanation:
3z²-6z+3=0
Divide all terms by 3.
3z² ÷ 3 = z²
-6z ÷ 3 = -2z
3 ÷ 3 = 1
The equation will be: z² - 2z + 1 = 0
Now factor the equation. Since, and factor ng positive 1 na kapag in-add ang sagot ay magiging negative 2 ay -1 · -1, and magiging factor ng equation ay:
(z - 1) (z - 1) = 0
z - 1 = 0 z - 1 = 0
z = 1 z = 1
FINAL ANSWER: {1}
