Given polynomials, identify: number of terms, degree, leading coefficient, constant term. Examples: '4x³ - 2x² + x - 7': terms=4, degree=3, leading coeff=4, constant=-7. 8 polynomials. Also: 'Write in standard form: 5 + 3x² - x' → '3x² - x + 5'. And: 'Is this a polynomial? 3x² + 1/x' → No (negative
