Answer:
Part 1) In the procedure
Part 2) In the procedure
Step-by-step explanation:
Part 1) Observing the graph
The roots are x=-1/2 and x=4
Remember that, the roots are the x-values when the value of y is equal to zero (the x-intercepts)
That's why Sheldon immediately realizes Howard's solution is incorrect
Part 2) we have

The formula to solve a quadratic equation of the form
is equal to
in this problem we have
equate the equation to zero
so
substitute
Howard's error is in this step, is wrong with the sign of the number 7, is positive instead of negative

Answer:
2. correct
3. addition property of equality
4. substitution property of equality
Step-by-step explanation:
You're asked for the Reasons, so you need to examine the Statements to see how you get from one line to the next.
The first line of Statement 2 differs from Statement 3 in that m∠GHI has been added to both sides of the equation (ignoring the typo in statement 3). The reason you can add the same thing to both sides of an equation is given by the <em>Addition Property of Equality</em>.
Statement 3 differs from Statement 4 in that one of the m∠GHI has been replaced by m∠JKL. We can do this replacement because those measures are equal to each other. Replacement of equals by equals is allowed by the <em>Substitution Property of Equality</em>.
