What is the sum of (6x^2-3x+2) and (-2x^2+7x-9)?

Answer and explanation

Correct answer: \(4x^2+4x-7\)

Add terms with the same power of \(x\): \(6x^2-2x^2=4x^2\), \(-3x+7x=4x\), and \(2-9=-7\). Hence, the sum is \(4x^2+4x-7\). In option D, the coefficients of \(x^2\) have been added incorrectly: \(6+(-2)=4\), not 8. Exam tip: While adding polynomials, group like terms first and carefully retain negative signs.
