explain how you would get this answer x2+x+33x−2 has the correct answer
To find the sum of the rational expressions, we need to combine like terms. In this case, we have x^2 terms, x terms, and constant terms.
Starting with the x^2 terms, we have x^2 - 23x - 2 + 0x^2 + 0x + 0 = x^2 - 23x - 2.
Moving on to the x terms, we have 0x^2 + 1x + 53x - 2 = 54x - 2.
Finally, we have the constant terms, which are -2 + 0 = -2.
Combining all these terms together, we get the sum x^2 - 23x - 2 + 54x - 2 = x^2 + 31x - 4.
Therefore, the correct answer is the fraction with numerator x squared plus x plus 33 and denominator 3x minus 2.
