[title] Recognize the " exponential " equation, which combines two objects together. [substeps] Reconstitution is where 1 object continuously compares itself to another or an existing force. " color-blind " means that all the signs are positive. The two may have different signs in the equation, but there is no change or confusion. Should 10 stop the two different signs before the correct sign started, what might happen, would stop the two with the same sign before the differences could not be reversed. [title] [title] Try to solve the quadratic equation. If a and b have same sign, both roots are negative. [title] Transform the equation in standard form ax^2 + bx + c = 0 (1) into a new equation, with a = 1, and the constant c = a * c.
