3t2 + 5t + 6t + 2t2 - 6t - 4is the same thing as 5t2 + 5t - 4.But that's not an 'answer'. There's no question in the original expression.
2t-4s
7s + 4t
It is: 3(t+3)
It is: 6(4x+3)
Placing a question mark at the end of a list of expressions or numbers does not make it a sensible question. What do you want? To evaluate it (impossible), factorise it, something else?
t + 5t + 5 = 6t + 5
-6 = 5t+24 -5t = 24+6 -5t = 30 t = -6
If t=1, then 5t = 5 and 5t + 5 = 10
no answer to t 5t - 5 = 5t +7 ( subtract 5t from both sides reducing to) -5 = +7 Negative 5 does not equal positive 7.
