Problem: How to solve quadratic equations with the " transforming method " 
Recall the rule of signs. 
If a and c have different signs, roots have different signs if a and c have same sign, roots have same sign. If a and b have different signs, both roots are positive. OPTIONS:
- Recognize the " exponential " equation, which combines two objects together. 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. Try to solve the quadratic equation.
- If a and b have same sign, both roots are negative. 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.

Answer: If a and b have same sign, both roots are negative. 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.


Problem: She then keeps adding more sand to the hill. Then a little boy joins her and just touches the hill, but walks away. he OPTIONS:
