Answer 2

hey ❤❤

Good Morning ❤❤

middle term of T² - 100T - 6000=0

Solution :--

T²-100T -6000=0

by using Dharacharya formula

T=[ -b±√{(b²-4ac)}]/2a

here ,

a=1,b= -100, c = -6000

T = [-(-100)±√{(-100)²-4×1×-6000}]/2

T= [100±√{10000+24000}]/2

T= [100±√{32000}]/2

T= [100±10√320]/2

T= [100±20√80]/2

T= [100±40√20]/2

T= [100±80√5]/2

take +ve and -ve sign

T=( 100+80√5)/2

and ,

T= (100-80√5)/2
