Question

is the sum of the roots of the equation ax^2+bx+c=0 is equal to the sum of their squares then-
(A) 2ac= ab+ c
(B) 2ac=b(a+b)
(C) a^2+b^2=c^2
(D)a^2+b^2=a +b​

Answer 1

Answer:

answer is option C

Step-by-step explanation:

Answer 2

Answer:

(B)

Step-by-step explanation:

LET the roots be m , n

m + n = -b/a , mn = c/a

m² + n² = m+n

(m+n)² = m+ n + 2mn

(bla)² = -b/a + 2c/a

2c/a = b²/a² + b/a

2ac = b² + ab

2ac = b(a +b)

answer is (B)
