Please use picture for the question not the writing Using the completing-the-square method, rewrite f(x)=x2 + 4x-1 in vertex form
Ofix) = (x+22+1
Of(x) = (x+22
O fx)= (x+22+ 4
Ofex) = (x+212-5

To complete the square, the same value needs to be added to both sides

To complete the square, Add 4 on both sides of the equation

Use a²+2ab+b²=(a+b)² to factor the expression

Move the constant to the right-hand side and change its sign

Calculate the difference

And, We are done solving!!~

The option that corresponds our final answer is option D...
