3(4a+b+2c)
yes it is
C2+6c-9
Without any signs between what appear to be terms, it is not possible to simplify.
It is -44 + 4a
6c.
Collect like terms: 11c+6d-5c-8d = 6c-2d
(5a - 4b) + (2c - 3b - 6c) + a =5a - 4b + 2c - 3b - 6c + a =(5a + a) + (-4b - 3b) + (2c - 6c) =[ 6a - 7b - 4c ].
5ab-2ab+4a-b+5b = 3ab+4a+4b
a2 - 4a + 4
48a3 + 32a2 + 4a = 4a(12a2 + 8a + 1)
I--2a+b=2c+2d II--2a+b=c+2d III--a+2b=3d * Here if we perform (I)-(II), we get, c=0 * Using the c we can prove b=0 using (I)-(III). * Now replace 'b' & 'c' as 0 in (I), then we get a=d. Email me at yash2008gates@gmail.com for any queries. I will be very thankful to receive your queries.
