In a standard binomial equation: ax² + bx + c = 0
To complete the square; divide the middle coefficient "b" in half and square it to find "c".
(-5/2)² = 25/4
x² - 5x + 25/4 = 25/4
completes the square:
(x - 5/2)² = 25/4
In order to solve the following system of equations by addition, we multiply both equations with a factor that will eliminate one variable. From the choices listed above, I believe the correct answer is option C. We have to first multiply the top equation by -3 and the bottom equation by 2. Doing such will eliminate the y variable term.
