X^4-33x^2+200=0 (factor that out)
<span>x^4-33x^2+200 -----> (x^2-8)(x^2-25)
</span>
new equation:
x^2-8=0 x^2-25=0 (solve for x for both equations)
x^2=8 x^2 =25
the x's are still squared so you have the square root both sides of the equations to get rid of the ^2:
x^2=8 x^2=25
x=
x=5
less than; Set A
It is less than, because if you add half of the sum of the least and greatest numbers of the set to the lowest number in the set, you get the median. The median of Set A was 17, and the Median of Set B was 17.5.
Set A is more variable in terms of range, because it has a larger range.
The 5th degrees could cancel out to be a polynomial of degree 4. Similarly for lower degrees.
<span>But it can't be a 6th degree.</span>
Look like B to me
It cant be C which has a negative slope.
