After simplifying (4x^2+3x+2x^2-3x+1), what will be its degree?

Answer and explanation

Correct answer: 2

Combining like terms gives \(4x^2+2x^2=6x^2\) and \(3x-3x=0\). Thus, the simplified expression is \(6x^2+1\). The highest power of \(x\) in it is 2, so the degree of the polynomial is 2. It is not 1 because the linear terms cancel, while the \(x^2\) term remains. Exam tip: simplify by combining like terms first, then identify the highest exponent of the variable left in the polynomial.
