if one root of the equation 4×2 – 2x + (k – 4) = 0 be the reciprocal of the other, then what is k? About the author Josie
Answer: Hi Mate !!! Let the roots be a and b a = 1/b as given one root is the reciprocal of other And we also know that product of zeros is equal to a × 1 / a = ( k – 4 ) / 4 =>. k -4 = 4 k = 8 Hope it helps!!!!! Step-by-step explanation: Reply
Step-by-step explanation: 4×2 – 2x + ( k – 4 ) = 0 8 – 2x = – k + 4 -2x = – k + 4 – 8 -2x = – k – 4 k = – 4 – 2x Reply
Answer:
Hi Mate !!!
Let the roots be a and b
a = 1/b as given one root is the reciprocal of other
And we also know that
product of zeros is equal to
a × 1 / a = ( k – 4 ) / 4
=>.
k -4 = 4
k = 8
Hope it helps!!!!!
Step-by-step explanation:
Step-by-step explanation:
4×2 – 2x + ( k – 4 ) = 0
8 – 2x = – k + 4
-2x = – k + 4 – 8
-2x = – k – 4
k = – 4 – 2x
