(x-43.45)(x+7.45)=0.
Step-by-step explanation:
We have the quadratic equation
i.e. ![d^{2}-36d-324=0](/tpl/images/0011/7713/380e1.png)
Now, the roots of the quadratic equation
are given by ![x=\frac{-b\pm \sqrt{b^{2}-4ac}}{2a}](/tpl/images/0011/7713/38a7d.png)
So, from the given equation, we have,
a = 1, b =-36 , c = -324.
Substituting the values in
, we get,
i.e.![x=\frac{36\pm \sqrt{1296+1296}}{2}](/tpl/images/0011/7713/84a16.png)
i.e.![x=\frac{36\pm \sqrt{2592}}{2}](/tpl/images/0011/7713/d4c87.png)
i.e.![x=\frac{36\pm 50.9}{2}](/tpl/images/0011/7713/f207a.png)
i.e.
and i.e. ![x=\frac{36-50.9}{2}](/tpl/images/0011/7713/cd45f.png)
i.e.
and i.e. ![x=\frac{-14.9}{2}](/tpl/images/0011/7713/79de1.png)
i.e. x = 43.45 and x = -7.45
Hence, the factored form of the given expression will be (x-43.45)(x+7.45)=0.
