Answer:
[tex]\lbrace8.4,0.6\rbrace[/tex]Step by step explanation:
Solve for x:
[tex]x^2-11x+5=-2x[/tex]As a first step, solve using inverse operations to solve equations:
[tex]\begin{gathered} x^2-11+2x+5=0 \\ x^2-9x+5=0 \end{gathered}[/tex]Now, to solve this quadratic function we need to use the quadratic formula:
[tex]\begin{gathered} x=\frac{-b\pm\sqrt[]{b^2-4ac}}{2a} \\ \text{where,} \\ ax^2+bx+c=0\text{ is the form of the function} \end{gathered}[/tex]Then, the solutions for the equation:
[tex]\begin{gathered} x_1=\frac{9+\sqrt[]{(-9)^2-4(1)(5)}}{2(1)}=8.4 \\ x_2=\frac{9-\sqrt[]{(-9)^2-4(1)(5)}}{2(1)}=0.6 \end{gathered}[/tex]
