C. -5 + 9 = 22 + 9 - 7 is the answer.
This is because when solved it’s : -52 = 15 which is false therefore there’s no solution.
(-5+8*i)+(-9+5*i) evaluates to <span>-14+13i</span>
Answer:
P(x)=(x-2)(x-4)(x+3)(x+6)
Step-by-step explanation:
Given: P(x)=x⁴+3x³-28x²-36x+144
It is a polynomial with degree 4.
It should maximum four factor.
Hit and trial error method.
Put x = 2 into P(x)
P(2)=2⁴+3×2³-28×2²-36×2+144
P(2) = 0
So, x-2 would be factor of P(x)
Now divide x⁴+3x³-28x²-36x+144 by x-2 to get another factors


Put x = 4
now divide
by x-4


Now factor 
Complete factor of P(x)
P(x)=(x-2)(x-4)(x+3)(x+6)
Answer:
if you want it in standard form it would be −1/4x-1/2x-5/6
If you want it simplified it would be -3x/4-5/6
