We attempt to nd two numbers that add to give 9 and multiply to give 14, and the numbers that do this are 2 and 7. Therefore. x2 + 9x + 14 = (x + 2)(x + 7) Again, this equation shouldn't be believed until the right hand side is expanded, and is shown to equal x2 + 9x + 14. Example 2 : Factorize x2 + 7x 18. .

T = CN + F. Read the problem carefully so that you can fill in the equation with the values you know: “your total costs last month were $635” T = $635; ”Each card costs $2” C = $2/item; “you have monthly fixed costs of $125” F = $125. 635 = 2N + 125. Notice that there is one variable left in the equation.
