Answer:
C: isolate the x squared by using inverse operations
Step-by-step explanation:
This method of solving quadratic equation is used when there is only x² term and no x term. Thus;
For example, we have a quadratic equation;
x² - 1 = 80
To solve this by square root method, the first step we have to take is to isolate the x² term by inverse operation which is by addition of 1 to both sides to get rid of the -1 on the left side so that x² can be isolated.
Given :
Andrew has already played 32 minutes on his video game this morning and wants to play an additional 15 minutes on each of x games after school today.
To Find :
Which equation can be used to find y, the total minutes Andrew will play video games today.
Solution :
Number of minutes he play after school time, n = 15x .
Number of minutes already played, c = 32 .
So, total number of minutes he play games for today is :
y = n + c
y = 15x + 32
Therefore, equation which is useful to find number of minutes video game played per day is y = 15x + 32 .
