Answer:
x = −2 or x = 4.23606797749979 or x = −0.2360679774997898
Step-by-step explanation:
Subtract x^3-2x^2-9x-2 from both sides.
0 − (x3−2x2−9x−2) = x3−2x2−9x−2 − (x3−2x2−9x−2)
−x3+2x2+9x+2=0
Factor left side of equation.
(−x−2)(x2−4x−1)=0
Set factors equal to 0.
−x−2=0 or x2−4x−1=0
The answer of the factored polynomial is
(X+2)(2x+1)
Some of the fertilizer can run off into streams and can harm fish and get in the streams
-8r on both sides; -2r=16; now divide by -2; r=-8
Answer:
