Q. Solve by completing the square.\newliner2+20r=−31r^2 + 20r = -31\newlineWrite your answers as integers, proper or improper fractions in simplest form, or decimals rounded to the nearest hundredth.\newliner=r = _____ or r=r = _____
  1. Write equation in form: Write the equation in the form of r2+br=cr^2 + br = c. The given equation is already in this form: r2+20r=−31r^2 + 20r = -31.
  2. Move constant term: Move the constant term to the right side of the equation.\newlineAdd 3131 to both sides to isolate the r2r^2 and rr terms on the left side.\newliner2+20r+31=−31+31r^2 + 20r + 31 = -31 + 31\newliner2+20r=0r^2 + 20r = 0
