Answer: x=1 or x=−3 or x=−9
Step-by-step explanation:
[tex]x^{3} + 11x^{2} +15x-27 = 0[/tex]
Let's solve your equation step-by-step.
[tex]x^{3} + 11x^{2} +15x-27 = 0[/tex]
Step 1: Factor left side of equation.
(x−1)(x+3)(x+9)=0
Step 2: Set factors equal to 0.
x−1=0 or x+3=0 or x+9=0
x=1 or x=−3 or x=−9
Answer:
x=1 or x=−3 or x=−9
