Answer 2

Answer:

Answer is 43

Step by step explanation:

we have a formula (a-b)2=a2+b2-2ab

=(1/2a-3b)2

=1/4a2+9b2-2×1/2a×3b

=1/4a2+9b2-3b/a

in the given question a=-1,b,=2,c=1 substitute in 1/4a2+9b2-3b/a

=1/4×(-1)2+9(2)2-3(2)/-1

=1/4×1+9(4)-6/-1

=1/4+36+6/1

=1/4+36+6

=now take Lcm of 4,1,1

=1×4+4×36+4×6

=4+144+24/4

=172/4

=43
