1) ( r - 6 ) ( r + 9 )
simplify this expression ! answer this

(r-6) (r + 9) = r^2 + 3r - 54

Hopefully this helps.

r2 + 3r - 54 is correct (MathPapa)

i think there was a typo. you wrote pat brings 3 quarts of ice-cream to the party. each serving of ice-cream is 1 6 quart. how many total servings of ice-cream does pat bring to the party? i think the bold is supposed to be 1/6. so 1 quart of ice cream = 6 servings. 6 * 3 = 18.
