(t2 - 8t - 7) - (t2 + 5t - 6)
=t2 - t2 - 8t - 5t - 7 + 6
= -13t-1

Answer:

-13t-1

Step-by-step explanation:

Given two equations

t2 - 8t - 7            ----------------- (1)

t2 + 5t - 6            ----------------- (2)

Now subtracting (2) from (1), we get

( t2 - 8t - 7 ) - ( t2 + 5t - 6  )

t2 - 8t - 7 - t2 - 5t + 6

-13t-1

Therefore, answer is -13t-1
