An equation is formed of two equal expressions. The missing pieces of the solution of the quadratic equation are 50, 3, and -8.
<h3>What is an equation?</h3>
An equation is formed when two equal expressions are equated together with the help of an equal sign '='.
To fill the missing piece of the solution of the quadratic equation, you need to balance each of the equations. Therefore, the solution to the problem can be written as,
![-32 = 2(x^2 + 10x)\\\\-32 + 50 = 2(x^2 + 10x + 25)\\\\18 = 2(x + 5)^2\\\\9 = (x + 5)2\\\\\pm 3= x + 5\\\\x = -2\ \ {\rm or}\ \ x = -8](https://tex.z-dn.net/?f=-32%20%3D%202%28x%5E2%20%2B%2010x%29%5C%5C%5C%5C-32%20%2B%2050%20%3D%202%28x%5E2%20%2B%2010x%20%2B%2025%29%5C%5C%5C%5C18%20%3D%202%28x%20%2B%205%29%5E2%5C%5C%5C%5C9%20%3D%20%28x%20%2B%205%292%5C%5C%5C%5C%5Cpm%203%3D%20x%20%2B%205%5C%5C%5C%5Cx%20%3D%20-2%5C%20%5C%20%7B%5Crm%20or%7D%5C%20%5C%20x%20%3D%20-8)
Thus, the solution of the quadratic equation is -2 or -8.
Hence, the missing pieces of the solution of the quadratic equation are 50, 3, and -8.
