Question

If K square - 8 K + 16 is equal to zero has equal roots then find the value of k

Answer 1

HEYA ✌✌✌

HERE IS YOUR ANSWER.

IF THE POLYNOMIAL HAS EQUAL ROOTS THEN ,

D = 0

K^2 -8K +16

A= K , B = -8K , C = 16

D = B^2 -4AC

B^2-4AC = 0

(-8K)^2 - 4 ×K × 16 = 0

64K^2 - 64 K = 0

64 K ( K-1)

64 K = 0 AND (K-1) = 0

K = 0/64 AND K = 0 +1

K = 0 AND K = 1

.: VALUE OF K IS 0 AND 1 .

HOPE IT WILL HELPS YOU . :--)
