Question

question. express (x - 2)^2 as a trinomial in standard form. answer. attempt 1 out of 2

Explanation:

Step1: Recall the formula $(a - b)^2=a^{2}-2ab + b^{2}$

Here $a = x$ and $b = 2$.

Step2: Substitute values into formula

$(x - 2)^2=x^{2}-2\times x\times2+2^{2}$

Step3: Simplify the expression

$x^{2}-4x + 4$
