X +9 x +3 (x+9)(x+2) - 8(x+3)
------ - --------- = ---------------------------
8 x +2 8(x+2)
do you think it in this way or more simplified ?
Hello,
P(x)=(x-2)(x²-3)=x^3-2x²-3x+6
==========================
1/2. Because 3 cancel 3 and 2 can go in 4 twice.

Answer:
Step-by-step explanation:
xy = 42
x+y = - 2 Substitute into the top equation
y = -2 - x Put in for y
x(-2 - x) = 42 Remove the brackets
-2x - x^2 = 42 Subtract 42 from both sides.
-2x - x^2 - 42 = 0 Put in the more normal order.
-x^2 - 2x - 42 = 0 Multiply by -1
x^2 + 2x + 42 = 0
This cannot be factored. It gives complex roots as it is written. I will give you the answer but I kind of doubt the question is correct.
x1 = - 1 + 6.40i
x2 = -1 - 6.40i
