Question

if A and B are the roots of equation X square minus x + 1 = 20 then what is a square + b square​

Answer 1

Answer: (A + B)^2 = 160000

Step-by-step explanation:

ATQ : X – x + 1 = √A + B

=> x–x +1 = 20

=> √A+B = 20

=> A+B = 20^2

=> A+B = 400

=> A^2 + B^2 = 400^2

=>(A + B)^2 = 160000
