Which of the following circumstances would likely make factoring the best method for solving a quadratic equation?
1 answer:
Answer:
Option D.
Step-by-step explanation:
We need to find the circumstances that would likely make factoring the best method for solving a quadratic equation.
A quadratic equation is prime if its factors can not possible. So, option A is incorrect.
In a quadratic equation leading coefficient can not be zero. So, option B is incorrect.
For large numbers (coefficient or constant), quadratic formula is best method. So, option C is incorrect.
The difference of 2 perfect squares is:
In this case factoring is the best method.
Therefore, the correct option is D.

Answer:
B) Vertex (1,2), maximum
Step-by-step explanation:
First, determine if the graph has a maximum or a minimum value. Since the graph opens downwards, it has a <u>maximum</u> value.
The maximum is the point that has the greatest y value. We can see that the greatest y value is at . Going down two units from that spot, we can see that the x value is at
. We can plug those into the vertex form,
. By plugging in we get the point
.
