Evaluate x² + 2x - 4 if x = -4.

the answer is ;4

Step-by-step explanation:

4

x2+2x+4/4ix

Step-by-step explanation: −4fix+x2+2x+−x2=−4+−x2

−4fix+2x=−x2−4

Step 2: Add -2x to both sides.

−4fix+2x+−2x=−x2−4+−2x

−4fix=−x2−2x−4

Step 3: Divide both sides by -4ix.

−4fix/-4xi= −x2−2x−4/4xi

step-by-step explanation:

pleaze mark brainliest!

none of the above.

for one of the equations to be used in the process, there has to be a term in the equation since squared is .

since there is only a term in the first equation, we cannot derive a from completing the square.
