Question

factorise: 7/3-x/3-x²​

Answer 1

Step-by-step explanation:

I used completing the square method in which you first half the middle term that is b/2 then we square it and add as well as subtract it from the whole equation, then we group it so as to make either the (a+b)^2 or (a-b)^2 as one of the term, then we equate the whole equation to zero and solve it for x
