By working a few algebra word problems each day, you’ll be able to fine-tune your solving methods and work on any of the rough parts.If algebra word problems are giving you trouble in class, working with a private math tutor can help you keep up with the math topics.
Having a written record of each variable also helps when it comes time to give your solution, as you know what variable has the answer in it!
Writing down notes also functions as a way to double-check when you’ve got your solution ready.
When you’re solving an algebra problem in your head, you won’t have any way to go back and walk through your solution again if you missed a step.
Check −14: −14(−14 2) = (−14)×(−12) = 168 YES Check 12: 12(12 2) = 12×14 = 168 YES So there are two solutions: -14 and -12 is one, 12 and 14 is the other.
Note: we could have also tried "guess and check": And so L = 8 or −14 There are two solutions to the quadratic equation, but only one of them is possible since the length of the room cannot be negative!
