Question

What is the equivalent form to the equation y = (1 - 1)2? Fill in the blanks below (pay attention to the signs in the equation). 2. +

Answer 1

Answer:

x^2 - 2x + 1

Explanation:

Given the below equation;

$y=(x-1)^2$

The above can be rewritten as;

$y=(x-1)(x-1)_{}$

To expand the above, all we need to do is use all the terms in the 1st parentheses and multiply all the terms in the 2nd parentheses as shown below;

$\begin{gathered} y=x^2-x-x+1 \\ y=x^2-2x+1 \end{gathered}$
