Question
Express left bracket, x, minus, 1, right bracket, squared(x−1) 2 as a trinomial in standard form.
Solution
The expression (x - 1)^2 can be expanded into a trinomial by using the formula (a - b)^2 = a^2 - 2ab + b^2.
Here, a is x and b is 1.
So, (x - 1)^2 = x^2 - 2x1 + 1^2 = x^2 - 2x + 1.
Therefore, the trinomial in standard form is x^2 - 2x + 1.
