Question

(5+2root3)&(5-2root3)find quardric polynomial

Answer 1

Sum of the roots = (5 + 2root3) + (5 - 2root3) = 10
Product of the roots = (5 + 2root3)*(5 - 2root3) = 25 - 12 = 13
Equation of polynomial is -->  x^2 - (sum of roots)*x + (product of roots) = 0
Hence, quadratic polynomial becomes -->  x^2 - 10x + 13 = 0
