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...

answer: 370

step-by-step explanation:

remember use pemdas! there are no parentheses or exponents so lets move onto the first part of the equation: multiplication and division. first, lets break the first part of the equation up into something easier using the distributive property. 28 * 12= (20 *12) + (8*12) you know that 20*12 is 240 and 8*12 is 96. add them and you get 336. then, lets solve the last part of the equation (the last part of pemdas is addition and subtraction). 336 plus 34 is 370. hope this !
