(adsbygoogle = window.adsbygoogle || []).push({}); 1. The problem statement, all variables and given/known data

I'm sorry this doesnt look too nice but it is supposed to be two matricces.

Show:

|1 a_{1}-b_{1}a_{1}+b_{1}| |1 a_{1}b_{1}|

|1 a_{2}-b_{2}a_{2}+b_{2}|=2*|1 a_{2}b_{2}|

|1 a_{3}-b_{3}a_{3}+b_{3}| |1 a_{3}b_{3}|

without evaluating the determinants.

2. Relevant equations

3. The attempt at a solution

It pretty obviously has got something to do with the 3. binomial formula and the rule that λ*A = λ*every value in the matrix.

I really don't know where to start on this, since I can't evaluate the determinants.

I'm pretty sure there is an easy way to do this, but I just can't see it.

Help is very much appreciated!

Thank you
