Recall the Remainder Theorem: if a polynomial \( P(x) \) is divided by \( (x - c) \), the remainder is simply \( P(c) \).
Desmos Shortcut: Enter the polynomial with a slider for the variable. In the next line, evaluate \( P(2) \) and adjust the slider until it equals 0.
By the Polynomial Remainder Theorem, dividing \( P(x) \) by \( (x - c) \) results in a remainder equal to \( P(c) \). Here, \( c = 2 \) and \( P(2) = 0 \). Substitute \( x = 2 \) into \( P(x) \) and equate to 0 to solve for the missing cons...
