Step-by-step explanation:
Negative times negative is positive.
-3(-7) = 21
Answer:
(x+4)(x+8)
Step-by-step explanation:
Factor x²+12x+32 using the AC method.
We can use the formula y2-y1/x2-x1 to find the slope.
1. 2-(-15)/12-5 gives us 17/7. The slope is 17/7.
2. -5-(-20)/6-(-18) gives us 15/24. We can simplify this to 5/8. The slope is 5/8.
3. -19-(-19)/-17-(-18) is 0/1. The slope is 0.
4. -17-3/-11-(-1) is -20/-10. The slope is 2.
