In this polynomial 2x⁴+3x²+5 The highest power is 4 so,it's degree is 4

More information=>

Degree of polynomial:

• Zero degree polynomial => A polynomial in which all coefficient makes zero e.g.,0x²+0x+0
• Degree of constant polynomial => The degree of any constant is 0 .A constant term can be written along with variable as e.g., 6x⁰ as power 0 is 1 and it becomes 6*1= 6
• Linear polynomial=> Having degree is called linear polynomial e.g., 3x+4y
• quadratic polynomial=> having degree 2 is called quadratic polynomial e.g., 2x²+3x+5
• Cubic polynomial=> having degree 3 e.g.,=> 3x³+3x+3
• Quartic polynomial=>having degree 4 is called quartic polynomial e.g., 4x⁴+3x³+2x+5
