Question:
<p>If <span class="math-tex">\((x+1)^{3}=x^{3}+1\)</span> is expressed as a quadratic equation in the form <span class="math-tex">\(p x^{2}+q x+r=0\)</span>, then the value of <span class="math-tex">\(p-q+r\)</span> is:</p>
<p style="display:inline">3</p>
<p style="display:inline">1</p>
<p style="display:inline">0</p>
<p style="display:inline">6</p>
Step-by-Step Solution
Key Concept: Expand the binomial expression $(x+1)^3$ and simplify the equation to identify the coefficients $p, q,$ and $r$ in the standard quadratic form.
<p>0</p>
