Question

Quizplus · Accepted Answer

To multiply the two binomials $(x - 1)(5x + 9)$, we use the distributive property (also known as FOIL - First, Outer, Inner, Last):- First: $x \cdot 5x = 5x^2$- Outer: $x \cdot 9 = 9x$- Inner: $-1 \cdot 5x = -5x$- Last: $-1 \cdot 9 = -9$Adding these together: $5x^2 + 9x - 5x - 9 = 5x^2 + 4x - 9$.
