Explanation of why the following statement is incorrect.
(x + 3)(x -4) < 7, and explain why it is incorrect.
To solve (x + 3)(x -4) < 7, start by setting (x + 3) = 7 and (x - 4) = 7.
Now solve the inequality.
Provide a detailed explanation of why using this method to solve the inequality is incorrect.
I am not that good at math. I appreciate any help anyone cam provide. Thanks Mike...Thank you for past help
You can't set each part equal to 7. That only works when you set each part equal to 0. Using zero works because we know if something times something = 0 then one of the factors has to = 0.
multiply first
x2 -x -12 <7
x2 -x - 19 <0 Now, you can finish the problem.
