Question

write the degree of the following polynomial 5xto the power of 3 +4xto the power of 2 +5x step by step ​

Answer 1

Answer:

5x³+4x²+5x

variable term= 5x³, 4x², 5x

exponent of x³= 5

exponent of x²=4

exponent of x=5

degree of polynomial= 5x³

Answer 2

Answer:Answer:

The value of a polynomial obtained on putting a particular value of the variable is called the value of the polynomial.

 

The value of a polynomial p(x) at x= a(let) is denoted by p(a).

 

----------------------------------------------------------------------------------------------------

Solution:

i)                  

p(x) = 5x - 4x² + 3

 

On putting x=0 ,

 

p(0) = 5(0) - 4(0)² + 3

 

= 0 - 0 +3=3

= 3

 

ii)

(x) = 5x - 4x² + 3

 

On putting x= -1,

 

p(-1) = 5(-1) - 4(-1)²+ 3

= -5 - 4(1) + 3

 

= -5-4+3= -9+3= -6

 

= -6

 

 

iii)

p(x) = 5x - 4x² + 3

 

On putting x=2

 

p(2) = 5(2) - 4(2)² + 3

= 10 – 16 + 3 = -6+3

 

= -3
