Question

find all zeros of the function
x^2+10x+23

Answer 1

\[x1=(-10+\sqrt{8})/2=-3.586; x2=(-10-\sqrt{8})/2=-6.414\]

Answer 2

\[\huge{x^2+10x+23}\]

Let this equation be p(x)

so p(x)=0

\[\huge{x^2+10x+23=0}\]
\[\huge{ax^2+bx+c=0}\] --- Just compare these equations that is 1) p(x) and 2) general form of a quadratic equation :

The roots of a quadratic equation :
\[\huge{x=\frac{-b\pm\sqrt{b^2-4ac}}{2a}}\]

put a = 1 , b = 10 , c = 23

Answer 3

can you do this now @dorkkk
