Question

If the sum of the roots of the equation ax²+bx+c=0 is equal to the sum of squares of their reciprocals then bc², ca² , ab² are in​

Answer 1

Answer:

Rinse the cut or wound with water and apply pressure with sterile gauze, a bandage, or a clean cloth. If blood soaks through the bandage, place another bandage on top of the first and keep applying pressure. Raise the injured body part to slow bleeding. When bleeding stops, cover the wound with a new, clean bandage.

Answer 2

Answer:

hy

Step-by-step explanation:

let P and Q are roots of eqn

P + Q = -b/a

PQ = c/a

a/c to question,

P + Q = 1/P² + 1/Q²

-b/a ={ ( P + Q)²-2PQ }/P²Q²

-b/a = { b²/a² -2c/a)/(c/a)²

-b×c²/a³ = b²/a² -2c/a

2c/a = b²/a² + bc²/a³ = b( ab + c²)/a³

2ca² = b²a + bc²

2 = b²a/a²c + bc²/a²c

= b²/ac + bc/a²

b²/ac + bc/a² = 2 ( answer)
