1.	Let (1+x+x2)2014=a0+a1x+a2x2+a3x3+....+a4028x4028 and letA=a0−a3+a6−......+a4026,B=a1−a4+a7−......−a4027,C=a2−a5+a8−......+a4028Then
Answer» $Let (1 + x + x^{2})^{2014} = a_{0} + a_{1} x + a_{2} x^{2} + a_{3} x^{3} + . . . . + a_{4028} x^{4028} and let A = a_{0} - a_{3} + a_{6} - . . . . . . + a_{4026,} B = a_{1} - a_{4} + a_{7} - . . . . . . - a_{4027,} C = a_{2} - a_{5} + a_{8} - . . . . . . + a_{4028} Then$
