Answer:
f(x)=(x-2)(x+2)(x-5)
Step-by-step explanation:
f(x)=x³-5x²+4x-20 1. Just group randomly
f(x)=x²(x-5)+4(x-5) 2. Factor the groupings
f(x)=(x²+4)(x-5)
<u>f(x)=(x-2)(x+2)(x-5)</u> 3. Factor the difference of two squares
Answer:
Step 3: Add those deviations together.
Step-by-step explanation:
Answer:
D -13
Step-by-step explanation:
5x - 3y - z if x = -2, y = 2, and z = -3
5x - 3y - z =
= 5(-2) - 3(2) - (-3)
= -10 - 6 + 3
= -16 + 3
= -13
