Answer:
One rational solution
Step-by-step explanation:
proof
5x2 - 2x - 3=0, the sum of coefficients is 5-2-3=0, so the equation has exactly two solutions, x=1, and x = -3/5 this last is the one rational solution
A. 24
=5x2+5x
Let's simplify step-by-step.
3x+3x2+2x2+2x
There was a 200% increase
The polynomial remainder theorem says that dividing a polynomial by leaves a remainder of if is a factor of . In this case, check and .
From the first equation,
and substituting into the second gives
