Question

solve this question class 10 ​

Answer 1

Step-by-step explanation:

16 x - 16/ x = 27

multiplying both side by x

16x²-16 = 27x

16x²-27x-16= 0

a = 16 , b = -27 , c = -16

x = -b±√D/2a

x = -b ± √ b²-4ac /2a

x = -(-27) ± √ (-27)²-4(16)(-16) / 2(16)

x = 27 ± √729+1024 / 32

x = 27 ±√1753 /32

x = 27 ± 42 / 32

x = 27+42/32 , 27-42/32

x = 69/32 , -15/32
