Question

How can 2x2 = x2 + 4x + 8 be set up as a system of equations?

Answer 1

We are asked in the problem to get the linear equations that results to 2x2 =x2 + 4x +8. In this case, the two equations on each sides can be equal to y in which the two equations are then identical. The systems of equations that has the right answer is C. 

Answer 2

Answer:

$y=2x^{2}$

$y=x^{2} +4x+8$

Step-by-step explanation:

we have

$2x^{2} =x^{2} +4x+8$ -----> original equation

To set up as a system of equations

Let the left side of the equation ------> equation A

Let the right side of the equation ------> equation B

so

$y=2x^{2}$ -------> equation A

$y=x^{2} +4x+8$ -----> equation B

The system of equations will have the same solutions for x that the original equation
