Step-by-step explanation:
This is your required solution..I hope it's up to the point..
Step-by-step explanation:
Given, quadratic polynomial is √3x2 - 8x + 4√3
= √3x2 - 6x - 2x + 4√3
= √3x2 - √3 * √3 * 2 * x - 2x + 4√3
= √3x(x - 2√3) - 2(x - 2√3)
= (x - 2√3)(√3x - 2)
The value of √3x2 - 8x + 4√3 is zero if x - 2√3 = 0 or √3x - 2 = 0
So, x = 2√3, 2/√3
Therefore, zeroes of x2 – 2x – 8 are 2√3 and 2/√3
Now, Sum of zeroes = 2√3 + 2/√3
= (2√3 * √3 + 2)/√3
= (2 * 3 + 2)/√3
= (6 + 2)/√3
= 8/√3
= -(-8)/√3
= -(Coefficient of x)/ (Coefficient of x2)
Product of zeroes = 2√3 * (2/√3)
= (2√3 * 2)/√3
= 4√3/√3
= Constant term/ (Coefficient of x2)
Hence, the relation between its zero and coefficients is verified.
