2018 GCE Paper 2, Question 1-3

[@LovelyMutukwa-jy8gb]

You teach very good sir,I understand your teachings very much

[@venaliciousmanga]

I don't know whether I'm the one who's confused or? But in the first question by finding the inverse of A. You didn't exchange the numbers in the main diagonal but you gave the 2 and 3 their negative numbers. Please help 😢

[@MxZulu]

He failed q1 completely, x is 3

Hello there Sir it's me Wilson watching from Lusaka chamba valley loving your teaching

[@davidkadobi7833]

on the inverse the adjoints are not swapped when multiplying by half sir. The 4 was supposed to be swapped with a 2

[@SafianAbdulBaaqi-zp3un]

Please check the entries in the leading diagonal.

[@user-km1wi2dz8x]

Did well but the major diagonal was not interchange why

[@SambaBanda]

Sir can you leave the inverse without multiplying

[@PatrickMwansa-ii4pg]

boss sorry you did not interchange the leading diagonals for the adjoint to find the inverse
