Question

multiply.
$(x + 6)(x + 3)$

$(x + 6)(x + 3)=\square$ (simplify your answer.)

Explanation:

Step1: Apply FOIL method

First terms: $x \cdot x = x^2$
Outer terms: $x \cdot 3 = 3x$
Inner terms: $6 \cdot x = 6x$
Last terms: $6 \cdot 3 = 18$
Combine these: $x^2 + 3x + 6x + 18$

Step2: Combine like terms

Add $3x$ and $6x$: $3x + 6x = 9x$
Simplified expression: $x^2 + 9x + 18$

Answer:

$x^2 + 9x + 18$
