Question

Simplify (t2+6t)/(t-1)- (7)/(t-1)

Answer 1

(8t-7)/t-1

Answer 2

can you explain this to me please?

Answer 3

t2 = 2t ya, so 2t+6t=8t then 8t/t-1 - 7/t-1 have the same denominator

Answer 4

no t2 = t^2

Answer 5

o sorry, ((x-7)(x+1))/(t-1)

Answer 6

Actually, luke, I think you switched the signs. I'm getting ((t + 7) (t - 1))/(t-1) which simplifies down to t+7

Answer 7

your right, i had -6t , damn!

Answer 8

Be careful with your language, please! But, yea, those signs can be tricky
