Answer:
8.−2x^2+6x
9.y-1
Step-by-step explanation:
8.(−2x)(x−3)
=(−2x)(x+−3)
=(−2x)(x)+(−2x)(−3)
=−2x^2+6x
9. y^2−y
y
= y^2−y
y
=y−1
Answer:
Internal validity
Step-by-step explanation:

Therefore, we can conclude that Internal validity refers to the degree to which changes in the dependent variable are due to the manipulation of the independent variable.
