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.
Answer:
Slope =-1/3
Step-by-step explanation:
(3,2)..... x1 =3, y1=2
(-3,4).... x2=-3, y2 =4
Slope=(y2-y1) /(x2-x1)
Slope=(4-2) /(-3-3)
Slope =2/(-6)
Slope=-1/3
