Question
Use the graph to solve the given equation. Check by substituting into the equation.$$x^{2}+8 x+15=0$$(GRAPH CANT COPY)
Step 1
The roots are where the function equals zero. This suggests that the factors are $(x+3)$ and $(x+5)$. So we can write the polynomial function as $f(x) = (x+3)(x+5)$. Show more…
