Answer:=6x2+5x + −4/15
Step-by-step explanation:Let's simplify step-by-step.
8x2−3x+13−(2x2−8x+3/5)
Distribute the Negative Sign:
=8x2−3x+13+−1(2x2−8x+3/5)
=8x2+−3x+13+−1(2x2)+−1(−8x)+−1(3/5)
=8x2+−3x+13+−2x2+8x+−3/5
Combine Like Terms:
=8x2+−3x+1/3+−2x2+8x+−3/5
=(8x2+−2x2)+(−3x+8x)+(1/3+−3/5)
=6x2+5x+−4/15
A polynomial has a root if it is a multiple of
So, if you want roots , your polynomial must be a multiple of
If we add another monomial, we would raise the degree, but we want it to be as low as possible. So, we can only add a multiplicative constant: your polynomial is
PEMDAS comes first. Instead of adding 9+2 first, they should've multiplied 2x3. The final answer would be 15.
