this is the formula because u can see from the name that we have to complete a whole square
wait m showing u an example how to do
you can also refer to ur books if u wish
01) 5x²-6x-2
v r thought to multiply throughout by the first coefficient
you have to do that in this particular sum as 5 is not a perfect square number and to use completing square method if u make it 25 by lets say multiplying throughout by 5 it will help u
but in the 2nd sun 4 is already a perfect square number (2)^2 so u do not need to multiply it agaib
again*
and if u want u can put my values and check.. the ans is correct
got it
