factor n^2-10n+24

Answers

factors of 24 that would also add up to -10 would be -12 and 2 soo. you would factor out the n's to get:
(n-12)(n+2)
Your question is : -

n² - 10n +24

we split -10 n into two numbers such that product is 24 and sum is -10n. We find the numbers be -6 and -4.

n² - 6n - 4n + 24

= n(n-6) - 4(n-6)

= (n-4)(n-6)

Titus works at a hotel. Part of his job is to keep the complimentary pitcher of water at least half full and always with ice. When he starts his shift, the water level shows 4 gallons, or 128 cups of water. As the shift progresses, he records the level of the water every 10 minutes. After 2 hours, he uses a regression calculator to compute an equation for the decrease in water. His equation is W –0.414t + 129.549, where t is the number of minutes and W is the level of water. According to the equation, after about how many minutes would the water level be less than or equal to 64 cups
