quadratic polynomial is given, 2√3x² - 5x + √3 .
2√3x² - 5x + √3 = 0
or, 2√3x² - 2x - 3x + √3 = 0
or, 2√3x² - 2x - √3 × √3 × x + √3 = 0
or, 2x(√3x - 1) - √3(√3x - 1) = 0
or, (2x - √3)(√3x - 1) = 0
or, x = √3/2 and 1/√3
verification : sum of roots = -b/a
LHS = sum of roots = √3/2 + 1/√3 = 5/2√3
RHS = -b/a = -(-5)/2√3 = 5/2√3
LHS = RHS
again, product of roots = c/a
LHS = √3/2 × 1/√3 = 1/2
RHS = √3/2√3 = 1/2
LHS = RHS
hence verified.
