There is no work to show. It is really just trial and error till you get the hang of it. You look at the multiples of the last term and find.which add or subtract to the middle terms coefficient. Use DeCartes law of signs to determine if it is plus or minus.
1. Does not factor solve using other method
2. (X-5)^2
2x-7=9
Add 7 to both sides
2x=16
Divide both sides by 2
x=8
Final answer: The number is 8
When simplifying an expression, you collect and simplify all the like terms. Since 8x and -12 aren’t like terms, you can’t substract 8-12
The Midpoint Formula works exactly the same way. If you need to find the point that is exactly halfway between two given points, just average the x-values and the y-values.
Hope this helps:)
