Combining the square of 4ab-2ab-6ab + 1 / 2Ab Merge congeners The square of 4ab-2ab-6ab + 1 / 2Ab


The square of 4ab-2ab-6ab + 1 / 2Ab
=Square of 4AB - square of 6ab - 2Ab + 1 / 2Ab
=-2ab²-3/2ab



-(3a2-4ab) + [A2-2 (2a + 2Ab)], where a = - 2


The original formula = - 3a2 + 4AB + a2-4a-4ab = - 2a2-4a, when a = - 2, the original formula = - 2 × (- 2) 2-4 × (- 2) = 0



1. Simplify 4a-2 (a-b) + (c + 2b-a)


Original formula = 4a-2a 2B C 2b-a = a 4B C
