Question

solve

Answer 1

solve what?

Answer 2

\[\frac{ [2(-1+h)^2 +4(-1+h)]+2 }{ h }\]

Answer 3

goodness. Give a minute...

Answer 4

Expand the square out, then factorize h out, then simplify!

Answer 5

would the square be factored out to (-1+2h+h^2) ?

Answer 6

NO, h² - 2h + 1

Answer 7

oh you start with the variables the the digits ?

Answer 8

oh alright

Answer 9

( h -1)² = h² - 2h + 1

Answer 10

then i get this and it looks wrong o.O \[-2-4h+2h^2-4+4h-2\]

Answer 11

= 2 (h² - 2h + 1) = 2h² - 4h + 2

Answer 12

but arent all the values that dont contain h cancel out at this point ?

Answer 13

( 2h² - 4h + 2) + ( 4h -4 ) + 2 = ...

Answer 14

2h^2-8

Answer 15

= 2h² / h = 2h

Answer 16

i get -8 too though ? :S

Answer 17

i have -2-4-2 :S

Answer 18

( 2h² - 4h + 2) + ( 4h -4 ) + 2 = ..

Answer 19

( a - b)² = a² - 2ab + b²
( h -1)² = h² - 2h + 1
