Question

(x^2-2x+1)^2 expand it

Answer 1

(x²-2x+1)²=(x²-2x+1)(x²-2x+1)

=x²(x²-2x+1)-2x(x²-2x+1)+(x²-2x+1)
=x⁴-2x³+x²-2x³+4x²-2x+x²-2x+1
=x⁴-4x³+2x²-4x+1


hope it helps

Answer 2

Hey!!!!


Given : (x^2 - 2x + 1)^2

LET US EXPAND IT NOW 》》》

= (x^2 - 2x + 1) (x^2 - 2x + 1)

OPEN BRACKET》》》

= x^4 - 2x^3 + x^2 -2x^2 + 4x^2 - 2x +x^2 - 2x + 1

ARRANGE LIKE TERMS AND OPWRATE LIKE TERMS 》》》

=x^4 - 2x^3 + 4x^2 -4x +1


======================
