Question

If f(x) = x-3x²+3x+1 find f(-1)​

Answer 1

answer is -6

Step-by-step explanation:

(-1)-3(-1)*+3(-1)+1

-1-3-3+1

-6

Answer 2

The correct answer is -6.

Explaination :-

Given :-

Factor of Quadratic polynomial x³ - 3x² + 3x + 1 is -1.

________________________

To Find :-

We have to solve Qiadratic polynomial x³ - 3x² + 3x + 1

_______________________

Solution :-

As, It is given that the factor of polynomial is -1. So, put Value of x in the polynomial.

A.T.Q

(-1)³ - 3(-1)² + 3(-1) + 1

-1 - 3 - 3 + 1

-7 + 1

-6

Hence, -6 is the answer.

____________________

Verification :-

For, Verification put value of x in the quadratic polynomial and put it equal to the -6. If our L.H.S is equal to R.H.S then it is verified.

(-1)³ - 3(-1)² + 3(-1) + 1 = -6

-1 - 3 - 3 + 1 = -6

-7 + 1 = -6

-6 = -6

L.H.S = R.H.S

Hence Verified
