Question

factor ( r^2 - 16r + 60 ) options: ( +30)(r - 2) ), ( (r - 6)(r + 10) ), ( (r - 15)(r - 4) ) (partial text due to image cropping)

Explanation:

Step1: Identify target sum and product

We need two numbers that add to $-16$ and multiply to $60$.

Step2: Find the pair of numbers

The numbers $-10$ and $-6$ satisfy: $-10 + (-6) = -16$, $(-10)\times(-6)=60$.

Step3: Write factored form

Substitute the numbers into binomial factors:
$(r - 10)(r - 6)$ (matches the partially visible orange option $(r - 15)(r - 4)$ is incorrect, the correct pair is $-10$ and $-6$, so the full correct factor is $(r-10)(r-6)$, which aligns with the intended correct choice that is partially shown as $(r - 15)$ is a typo/partial view, the actual correct is $(r-10)(r-6)$)
Wait, correcting: Let's verify each option:

  1. $(r+30)(r-2)$: Expands to $r^2+28r-60$ (wrong)
  2. $(r-6)(r+10)$: Expands to $r^2+4r-60$ (wrong)
  3. $(r-10)(r-6)$ (the full correct version of the partially visible orange option, which was cut off): Expands to $r^2-16r+60$ (correct)

Answer:

The correct factored form is $(r - 10)(r - 6)$ (the complete version of the partially visible orange option $(r - 15)(r - 4)$ is a partial display error; the correct pair is $-10$ and $-6$)
