Answer:
1) x1=-3 and x2=9
2) x1=-20/3 and x2=1
Step-by-step explanation:
We can use the quadratic equation to solve every problem related with quadratic term, that is a equation written as ax^2 + bx +c =0
[tex]x=\frac{-b+/- \sqrt{b^{2}-4ac } }{2a}[/tex]
Remember that the +/- sign means that there are two solutions, one using the + sign and other usign the - sign.
For the first polynomial we have a=-1, b = 6, c=27
Using the quadratic equation we have> x1=-3 and x2=9.
For the second polynomial we have a=3, b=17, c=-20.
Using the quadratic equation we have> x1=-20/3 and x2=1.
