Question

29. If the roots of the Quadratic equation
(a-b)x++(b-c)x+ (c-a)=0 are equal. Then prove
that 2a =b+c.
​

Answer 1

Answer:

this is a quadratic polynomial

2a = b + c

( a - b ) x ++ ( b - c ) x+ ( c - a ) = 0

(a-b) (a+b ) (c - c) = 0

all are cut because positive and negative a , b and c

Answer 2

Answer:

hey mate here is your answer

Step-by-step explanation:

the above equation is in the form of Ax square + bx + c is equal to zero

1. let A= (a-b)
2. let B=(b-c)
3. let C=(c-a)

USE, DELTA =B SQUARE - 4 AC

1. (b-c)2 = 4 - (a-b) (c-a)
