Question 437258: Make a graph to estimate the solutions of the equation. Check the solutions algebraically. Show all work.
x^2+12x+20=0
Answer by Gogonati(855) (Show Source): You can put this solution on YOUR website!
The graph of this function is a parabola, which opens up because a=1>0.
From its graph we see that the curve intersect the x-axis at (-10, 0) and (-2, 0).
Check: , for x=-10 and x=-2.
