Choice A is correct. The sum of the two polynomials is (3x2 − 5x + 2) + (5x2 − 2x − 6). This can be rewritten by combining like terms: (3x2 − 5x + 2 ) + (5x2 − 2x − 6) = (3x2 + 5x2) + (−5x − 2x) + (2 − 6) = 8x2 − 7x − 4.
Choice B is incorrect and may be the result of a sign error when combining the coefficients of the x-term. Choice C is incorrect and may be the result of adding the exponents, as well as the coefficients, of like terms. Choice D is incorrect and may be the result of a combination of the errors described in B and C.
