Describe Visualize Solutions of Simultaneous Equations ?
By drawing the graph of each equation in a system of equations, you can see a picture of the system's solutions.
For example, here's a system of equations:
x2 +y = 32x+y = 0
The solutions to this system are (3, -6) and (-1, 2). You can see all of this in the graph below. The parabola is the graph of the first equation, and the line is the graph of the second. You can see that their intersections are the solutions of the system.

Describe Square Roots? When a number is written inside a radical sign (√), the number is called the radicand, and we say that you are "taking the square root of" that number.
