Which expression is obtained by adding (x^2+4x-8) to (2x^2-5x+3)?

Answer and explanation

Correct answer: (3x^2-x-5)

Add the like terms in the two expressions: 2x^2+x^2=3x^2, -5x+4x=-x, and 3+(-8)=-5. Therefore, the sum is (3x^2-x-5). Option B incorrectly adds the x-terms. Exam tip: while adding polynomials, combine only terms with the same variable and exponent.
