Question

which of the following is linear polynomial x²+5, y-8, x³-2x+5​

Answer 1

Answer:

y-8

Step-by-step explanation:

so

x² + 5 is quadratic (as its highest power is 2)

x³ - 2x + 5 is cubic (highest power 3)

y - 8 is linear (highest power 1)

Answer 2

Answer:

Step-by-step explanation:

x square +5 is not a linear polynomial.

Because, variable power is 2 I.e, x to the power 2.

y-8 is a linear polynomial.

Because, the variable x has power 1.

x cube - 2x + 5 is not also a linear polynomial.

Because, it has 3 terms.

Hence, y - 8 is a perfect linear polynomial.
