What would be the solution for x in the rational equation:
x^2/(x-3)= (x+2)/(2x-5)
---- Cross-multiplying
<===== As the polynomial's LARGEST exponent is 3, there will be 3 solutions!!
Using the RATIONAL ROOT THEOREM, we find that 2 is a solution/zero of the above trinomial, so x = 2, or x - 2 = 0.
Hence, x - 2 is a factor of the polynomial.
Using SYNTHETIC DIVISION, or LONG DIVISION of POLYNOMIALS, the other factor of the polynomial is the quadratic,
, so the factors of
are:
.
As
CANNOT be factored with INTEGERS, its solutions/zeroes can be found, either by COMPLETING the SQUARE
or using the QUADRATIC EQUATION formula. Using the latter, we get:
<==== QUADRATIC EQUATION formula, where:
The 3 solutions/zeroes (1 RATIONAL and 2 IRRATIONAL):
