Question

x^2+3x+1=0 completing by square method​

Answer 1

Step-by-step explanation:

From the given x2+3x+1=0 , we can see that the coefficient of x^2 is already 1, so we can begin with the coefficient of x which is 3. The 3 will have to be divided by 2 then the result should be squared and the final result is 94 . ... The first 3 terms now will form a PST-perfect square trinomial.
