B.2
C.3
D.6
By using a quadratic equation the missing denominator of the solution is 4 plus or minus the square root of 2, all over is (B).2
For a Quadratic Equation
By Formula Method we get
So we have a Quadratic Equation that is
On Comparing we get,
a = 2
b = -8
c = 7
By substituting a, b, and c values we get
Therefore, by using a quadratic equation the missing denominator of the solution 4 plus or minus the square root of 2, all over is (B).2
Hence the correct answer is option B.2

Answer:
C. 3
Step-by-step explanation:
3x² + 4x - 2 = 0
[-4 +- sqrt(4² - 4(3)(-2))]/(2×3)
[-4 +- sqrt(40)]/6
[-4 +- 2sqrt(10)]/6
Simplifying, we get:
[-2 +- sqrt(10)]/3
