Question

[(a-ab) - (3a-1)] al cuadrado!

Answer 1

Explicación paso a paso:

a – ab – 3a + 1 = ( –2a – ab + 1 )²

( –2A – AB + 1 )² =

( –2A – AB + 1 ) × ( -2A – AB + 1 ) =

–2A =》4A² + 4A²B – 2A

–AB =》 2A²B + A²B² –AB

1 =》 -2A – AB + 1

4A²+4A²B–2A+2A²B+A²B²–AB–2A–AB+1 =

4A²B + A²B² – 2AB + 4A² – 4A + 1
