Question

find the zero of polynomial a2-2a+1

Answer 1

$= > \: a {}^{2} - 2a + 1 = 0$

$= > \: a {}^{2} - 1a - 1a + 1 = 0$

$= > \: a(a - 1) - 1(a - 1) = 0$

$= > \: (a - 1)(a - 1) = 0$

$= > \: \: a = 1$

$= > \: a = 1$

ZEROES OF POLYNOMIAL = (1,1)

HOPE ITS HELPFUL.....:-)

Answer 2

Answer:

The zero of the polynomial is 1.

Step-by-step explanation:

Zero of a polynomial means the value of the variable at which the expression is equal to zero.

a²-2a+1

= a²-a-a+1

= a(a-1)-1(a-1)

= (a-1)(a-1)

Now we equate it to zero.

(a-1)(a-1) = 0

For this the value of a-1 should be equal to zero.

Therefore, a-1 = 0

a-1 = 0

a = 1

a = 1

Hence 1,1 is the zero of a²-2a+1.
