X^2 + 6x = 13.  We are to "complete the square."

x^2 + 6x + (6/2)^2 - (6/2)^2 = 13

Then (x+3)^2 - 9 = 13, or (x+3)^2 = 22.

then x+3 = plus or minus sqrt(22), or     x = -3 plus or minus sqrt(22).

Given x^2 + 6x = 13, to complete the square we insert " 3^2 - 3^2 " between the "6x" and the "=" sign.

What is the value of y in the solution set of the system of linear equations shown
zaharov [31]
The answer will be 10 because you plug in y=-×+12 in the equation 4x-2y=36. After you solve and do distributive property your new equation should be 4x+2x-24=36, then you add the like terms of 4x and 2x which will equal to 6x and your new equation should be 6x-24=36. Add 24 from both sides and your equation should be 6x=60, then you divide 60 by 6 and your final answer will be x=10 or 10
