c2 + 4c + 4 =(c + 2) (c + 2)= (c + 2)2
4(a + 2b - 4c)
C2-4c+4=0 (c-2)(c-2) c-2=0 and c-2=0 C=2 and c=2 Put 2 in place of c and solve the equation
4c+1-5+2c = 6c-4.
2. c2 + c2 + 8 = 8c 2c2 - 8c + 8 = 0 c2 - 4c + 4 = 0 (c - 2)(c - 2) = 0 (c - 2)2 = 0 c - 2 = 0 c = 2
c2 + 4c + 4 =(c + 2) (c + 2)= (c + 2)2
4(a + 2b - 4c)
C2-4c+4=0 (c-2)(c-2) c-2=0 and c-2=0 C=2 and c=2 Put 2 in place of c and solve the equation
4c+1-5+2c = 6c-4.
2. c2 + c2 + 8 = 8c 2c2 - 8c + 8 = 0 c2 - 4c + 4 = 0 (c - 2)(c - 2) = 0 (c - 2)2 = 0 c - 2 = 0 c = 2
c2 - 4 = (c+2)*(c-2) So, dividing by (c+2) leaves the other factor: (c-2)
The GCF is 4.
4 cc
8c + 5 = 4c - 11Subtract 4c from each side:4c + 5 = -11Subtract 5 from each side:4c = -16Divide each side by 4:c = -4
1st:-4c- 11- 4c=4c+12- 4c2nd:-8c- 11+ 11=21+ 113rd:-8c/-8+ 32/-8c=-4
5P + 111 + 136 + 20 = 4c + 4 5P + 267 = 4c + 4 -4 -4 5P + 263 = 4c You cannot cimplify it anymore, unless by 'c' you meant 'P'. 5P + 263 = 4P -5P -5P 263(-1) = -P(-1) -263 = P
Without further information, all we can do is simplify: 4c + 4d = 4(c + d)
