Answer:
you can answe this by using a fimly tree for the numbers!
Step-by-step explanation:
Here is the work for this:
2,-5,-10
we start with 2,nothing can go into this number so we would have to put it as a whole, 2=1whole
next is -5,we need to make it a positive! after making it into a positive you must think,"How can I get 5,what two numbers make 5,well..5 along with 2 are PRIME NUMBERS so you can only multiply by 1 to get 5 or 2 however you CAN multiply/add two numbers to get 10. and it just so happends that 5x2=10. if you work backwords than you can get y=xto the 2nd power+3x-10. Thus By working backwords and mutiplying/deviding your fators you will get the correct answer!
I hope this helps you!
