Question

anonymous · Answer

have to find number and binomial

anonymous · Answer

i think that your supposed to find things that multiply that equal it

hartnn · Answer

there is a method for completing the square:
step 1: make co-efficient of x as 1 (ts already 1 here)
step 2 : identify the co-efficient of x (the number besides x)
what is it here?

anonymous · Answer

-4
?

hartnn · Answer

hartnn · Answer

step 4: now square it, what u get ?

anonymous · Answer

4

hartnn · Answer

that is correct .
sorry, i mistyped step 1 as 'step 1: make co-efficient of x as 1 (ts already 1 here)'
it should be 
'step 1: make co-efficient of x^2 as 1 (ts already 1 here)'

step 5 : now add and subtract 4 in x^2-4x+...
what u get ?
