Question

What is the result a2+bc-ba-ac

Answer 1

Step-by-step explanation:

a² + bc + ab + ac

rearrangeing the terms , we get

=a² + ab + ac + bc

=(a×a+a×b) + (a×c+b×c)

■ take a & c common in first & second brackets respectively, we get

= a (a + b ) + c (a + b)

■again take (a+b)

■ common, we get

= (a+b) (a+c)
