Question

solve this t²-15 by middle term splitting ​

Answer 1

Answer ↓

=t²-0t-15

=(t-√5 ) (t+√5)

The value of t²-15 is Zero when t-√15 =0 or t+√15 =0 when,t=√15 or t=-√15

Therefore,the zeroes of t²-15 are √15 and -√15

→Sum of zeroes =√15-(√15)=0 =-0/1=-(coefficient of t )/(coefficient of t²)

→Product of zeroes =(√15)(-√15)=-15 -15/1 =constant term /coefficient of x²

Here is the complete answer !
