Find the solution of this system of equations. <br> -2x-6y=-16<br> 4x-6y=-58
Yanka [14]
-(-2x-6y=-16)

2x+6y=16
4x-6y=-58

Y's cancel out, then add the rest

6x=-42

divide both sides by six

x=-7

plug x into any previous equation

2(-7)+6y=16

-14+6y=16

6y=30

y=5

Solve the quadratic equation by completing the square.<br> x^2+12x+52=0
White raven [17]

Answer:

(x + 6)² + 16 = 0

Step-by-step explanation:

To complete the square we will first need to get our equation to look like: x² + bx = c

Here we have x² + bx + c = 0 → x² + 12x + 52 = 0

  • First we need to subtract our c, in this case 52, from both sides to get x² + 12x = -52
  • We then need to add (\frac{b}{2} )^{2} to both sides of the equation
  • Here our b value is 12, so plugging this into our formula we get (\frac{12}{2} )^{2} =(6)^{2} =36
  • Adding 36 to both sides our equation becomes: x² + 12x + 36 = -52 + 36
  • Then combining like terms on the right side we get x² + 12x + 36 = -16
  • Now making our left side of the equation into a perfect square we get: (x + 6)² = -16
  • Finally adding the 16 to both sides of the equation we get: (x + 6)² + 16 = 0
