Question

Expand , ( -a - 1/2b - 6 ) ^2​

Answer 1

(-a-1/2 b-6)^2

=[(-a)+(-1/2 b)+(-6)]^2

=(-a)^2+(-1/2 b)^2+(-6)^2+2 (-a)(-1/2 b)+2 (-1/2 b)(-6)+2(-6)(-a)

=a^2+1/4 b^2+36+ab+6b+12a

Answer 2

(-a-1/2 b-6)^2

=[(-a)+(-1/2 b)+(-6)]^2

=(-a)^2+(-1/2 b)^2+(-6)^2+2 (-a)(-1/2 b)+2 (-1/2 b)(-6)+2(-6)(-a)

answer=a^2+1/4 b^2+36+ab+6b+12a
