Required Answer:-
Given:
- 3x² - 2√6x + 2 = 0
To Find:
- The roots of the given quadratic equation.
Solution:
We have,
➡ 3x² - 2√6x + 2 = 0
We need to split -2√6 into two parts whose sum is -2√6 and product is 6.
We found,
- -√6 - √6 = -2√6
- (-√6) × (-√6) = 6
Therefore,
➡ 3x² - √6x - √6x + 2 = 0
➡ √3x(√3x - √2) - √2(√3x - √2) = 0
➡ (√3x - √2)(√3x - √2) = 0
By zero product rule,
➡ Either (√3x - √2) = 0 or (√3x - √2) = 0
➡ x = √(2/3), √(2/3)
★ Hence, the roots of the given quadratic equation are √(2/3) and √(2/3) [Equal Roots]
Answer:
- Zeros are - √(2/3), √(2/3)
