Answer:
the polynomial cannot be factored
Step-by-step explanation:
The ratios of coefficients are 4:3 in the first and second pairs of terms, but the similarity ends there. The second pair of terms has no common factor but 2, and factoring that out leaves nothing in common with the rest of the expression:
= 3x^2(4x -3) +2(4x -3by)
If by=1, this would factor nicely as (3x^2 +2)(4x -3), but that is not the case. The "by" term effectively makes the expression unfactorable.
The expression cannot be factored.
Answer:
System has equal number of unknowns and equations.
Manipulation easily yielded expressions for 4 of the 7 unknowns.
However it seems that the remaining 3 unknowns x,y,z are not fixed by the equations. Different combinations (x0,y0,z0) seem possible without violating the system equations.
Is this possible, or did I most probably make a mistake in counting degrees of freedom?
Step-by-step explanation:
Use the Pythagprean theorem:
We have:
Substitute:
What numbers do you have to circle that are less than 25,000,003??
