Please show me how to factor this polynomial completely:
4x^2-20x+25
Thank you so much!! How would I graph these equations: (a) y = x + 3 (b) y = -1/3x (c) y = 1/3x (d) y = 3x?? If possible could you please show me how to graph all 4, because the more you show me, the easier it is for me to catch on. Graphing is very difficult for me.
