Question 64

Can you show me how to do 64?.
 
g(x)=x^2+10x+17 this cannot be factored, so we use quadratic formula to find zeros

plot-formula.mpl


in your case a=1, b=10, and c=17

plot-formula.mpl


plot-formula.mpl



plot-formula.mpl


plot-formula.mpl


plot-formula.mpl


plot-formula.mpl


=> zeros:
plot-formula.mpl
or
plot-formula.mpl



then

g(x)=
plot-formula.mpl
plot-formula.mpl
