(apex question, ? )
which polynomial represents the difference below
2x^2+7x+6
-
(3x^2-x)
a. -x^2+6x+6
b. 2x^2+4x+6
c. 2x^2+5x+6
d. -x^2+8x+6

With: label the vertices and all the elements needed. find x

Can someone check if i did this right since i really want to make sure it’s correct. if you do you so much

1- what do you think the product of a nonzero rational number and an irrational number is? is it rational or irrational? make use of variables, the closure property of integers, and possibly a proof by contradiction to prove your hypothesis.2- why do we have to specify that the rational number must be nonzero when we determine what the product of a nonzero rational number and an irrational number is? if the rational number were 0, would it give us the same result we found in the first question?
