16t²–40t–119=0
Write 119 as a factor of its prime factors.
119=7*17
Now,
See if we can find two numbers such that:
Product=16*(–119)
And,
Sum=–40
Thus, the numbers are: 28 and–68
Therefore, the equation becomes:
=〉16t²–68t+28t–119=0
=〉 4t(4t–17)–7(4t–17)=0
=〉(4t–7)(4t–17)=0
=〉t = 7/4 or 17/4
Thus,7/4 and17/4 are the required solutions!
