Factorising an equation is putting it into bracket form.
This has square numbers and so needs double brackets
(5x - y) (5x+y)
If you then check this by multiplying the brackets out again you will get:
5x^2 - 5xy + 5xy - y^2
The positive and negative 5xy's cancel each other out and you are left with its original form. Your answer is
(<span>5x - y) (5x+y)</span>
<span>x-axis: hours in increments of 1; y-axis: miles in increments of 5
You always want the constant numbers such as time on the x-axis
And since your y values are all large numbers and multiples of 5, it makes sense to use increments of 5</span>
