Answer:
x² + 10x - 24
Step-by-step explanation:
3x² - 12 + (x - 4)(2 - x) - (x² - 4x + 4)
= 3x² - 12 + (2x - x² - 8 + 4x) - x² + 4x - 4
= 3x² - 12 + 2x - x² - 8 + 4x - x² + 4x - 4
= x² + 10x - 24
Answer:
No solutions! :)
Step-by-step explanation:
To find the number of solutions in a problem we must solve it.
x+2x+7=3x-7
Firstly, combine common terms:
3x+7=3x-7
We can subtract 3x from both sides:
7=-7
The solution is 7=-7, which is no solution.
When a number is equal to a number in a solution, it has no solutions!
