When graphing, first we need to know what we're looking at. A simple graph will consist of long horizontal line called the x-axis, and long vertical line called the y-axis. Where these two lines meet is the origin with coordinates of (0,0). If you move from the origin the coordinates begin to change...

This is an example of a "work" problem. Typically there is a task that will be completed in some unit of time. The short-cut here is to think in terms of fractions. So, each person can do a portion (fraction) of work in a portion (fraction) of time. The first step is always the hardest...

Linear equations are the first step to understanding how graphing works. The default equation which will shortly become permanent in your knowledge of math is: y = mx + b This equation is the slope-intercept form for straight lines where 'm' represents the slope of the line, and 'b' represents...

When you distribute a constant, you multiply it. Here, it's to each value within the parentheses. So: x(3x2 - 5x +8) =  3x2(x) - 5x(x) + 8(x) When multiplying unknown variables (like 'x'), the product is that variable raised to the sum (addition) of their power. For example:...

Factoring trinomials is the opposite of multiplying, so we need to find 2 binomials. First, factor the 3x2, and place in the front of the binomial: (3a __)(a __) Next, to determine the second number in each binomial, list all possible factors of the last term, in this case 63. [what...
