105: Linear or Quadratic?
Is the expression x² + 6x = x² - 8x + 4 "quadratic" or linear?
Would you consider x² + 6x = x² - 8x + 4 "quadratic" or, because the x² terms can be subtracted from both sides, linear? #mathchat

This is not an expression, it is an equation. As such it is quadratic in form, but only has one solution.
