Question

if alpha and beta are the roots of the polynomial X square + bx + c find the value of Alpha square + beta square​

Answer 1

Answer:

Step-by-step explanation:

QUADRATIC EQUATION = x²+bx+c

alpha+beta = -B/A

                   =-b

alpha* beta = C/A

                   =c

(alpha + beta)²= alpha²+beta²+ 2*alpha*beta

(-b)²                 =alpha²+beta²+2*c

alpha²+beta²= b²-2c ANS
