Question

please find answer for the above question​

Answer 1

Answer:

x² -4x -71

Step-by-step explanation:

2+5√3 and 2-5√3 are given roots

sum of roots= 2+5√3 + 2-5√3=4

product of roots=(2+5√3)×(2-5√3)=(2)² -(5√3)² =4-25×3=4-75= -71 (a+b)(a-b)=a²-b²

forluma of quadratic quation=x²-(sum of roots)x + (product of roots)

therefore,x²-(4)x+(-71)

=x² -4x -71 is answer
