3 x 3 x 3 x 7 x 7
1 x 1323, 3 x 441, 7 x 189, 9 x 147, 21 x 63, 27 x 49.
That's the same as 6/7 x 6/7 = 36/49
x+3/4 = 7/8 Is the same as: x+6/8 = 7/8 x = 7/8- 6/8 x = 1/8
You have : -------------- ( x + 1 ) / ( x ) = ( -7 ) / ( x - 12 ) Multiply both sides by ( x ) ( x - 12 ) and get : ( x + 1 ) ( x - 12 ) = ( -7 ) ( x ) x^2 - 12x + x - 12 = -7x x^2 - 4x - 12 = 0 Factor the above : ( x - 6 ) ( x + 2 ) = 0 There are two roots : x = 6 <------------------ x = -2 <---------------
3 x 3 x 3 x 7 x 7 = 1323

3 x 3 x 3 x 7 x 73^3 x 7^2
That's the same as 6/7 x 6/7 = 36/49
you must get the reciprocal of 7 over 6 which is 6 over 7. Then we proceed to multiplication. 280 x 6/7 = 40 x 6 = 240. That's it I hope I hep yoiu. :)
