Answer: First option.
Step-by-step explanation:
1. To solve this problem you can applly the quadratic formula, which is shown below:
[tex]x=\frac{-b+/-\sqrt{b^{2}-4ac}}{2a}[/tex]
2. The quadratic equation is:
[tex]x^{2}-4x-9-29=0\\x^{2}-4x-38=0[/tex]
3. Then:
a=1
b=-4
c=-38
4. Therefore, when you substitute these values into the quadratic formula, you obtain the following result:
[tex]x=\frac{-(-4)+/-\sqrt{(-4)^{2}-4(1)(-38)}}{2(1)}[/tex]
x=2±√42
