QUESTION 2
Easy
Write polynomials of degree 1,2, and 3.
SOLUTION
Polynomial of degree 1 (linear) : \(2x + 5\)
Polynomial of degree 2 (quadratic) : \( x^2 − 4x + 10 \)
Polynomial of degree 3 (cubic) : \( 2x^3 + x^2 + 4 \)
Polynomial of degree 2 (quadratic) : \( x^2 − 4x + 10 \)
Polynomial of degree 3 (cubic) : \( 2x^3 + x^2 + 4 \)
🏆
Final Answer : \(2x + 5, x^2 − 4x + 10, 2x^3 + x^2 + 4\)
Concept Note
The highest power of the variable in the polynomial is called its degree.
