If ax power n-1 + bx power n-2 + cx power n-3 is a cubic polynomial, where n belongs to N, then find the value of 'n'. ​

Answer»

ong>Given : axⁿ⁻¹ +bxⁿ⁻²  + cxⁿ⁻³ is  a cubic polynomial where n belongs to N,

To Find : the value of 'n'

Solution:

axⁿ⁻¹ +bxⁿ⁻²  + cxⁿ⁻³ is  a cubic polynomial  

so maximum power to x should be 3

and one of the power to x should be 3

case 1 :  n - 1 = 3

=> n = 4

n - 2 = 4 - 2 = 2

n - 3 = 4 - 3 = 1

=> ax³ + bx²  + CX  

Hence n = 4

case 2 :

n - 2 = 3

=> n = 5

n - 1 = 4   > 3  Hence not a cubic polynomial

case 3 :

n - 3 = 3

=> n = 6

n - 1 = 5   > 3  Hence not a cubic polynomial

Value of n = 4

Answer this question please, I'll mark the brainliest if ur correct

Answer»

ong>Answer:

option (1) 4,1

Step-by-step explanation:

when you take (x,y) = (4, –1)

means x= 4, & y = 1 , so

it satisfies both the equation

equation 1

2x – y = 9

2×(4) – (–1) = 9

8+1= 9

9=9

equation 2

x+y = 3

4+(-1)=3

4-1=3

3=3

so, L.H.S = R.H.S in both equation,

hence , (4,1) is correct answer...

A^2b^2x^2-(a^2+b^2)x+1=0​

Answer»

ong>Step-by-step explanation:

we have , a²b² x² + b² x²+ b² x - a² x-1 =0

[ -1 x a² b² = -a²b² = -a² b² = -a² X b²]

= a² b² x² + b² x - a² x - 1 = 0

= b²x ( a² x + 1 ) -1 ( a² x -1 = 0 )

= ( a² x + 1 ) ( b² x - 1 ) = 0

= a² x + 1 = 0 or b² x - 1 = 0
