How do you use the graph to solve #0=x^2+3x+2#?

Answer 1

Julia Adams

Solution: #x= -1 or x = -2#

#x^2+3x+2 =0 or (x+2)(x+1)=0# In graph , x -intercept is at #x= -1 and x= -2# graph{x^2+3x+2 [-10, 10, -5, 5]} [Ans]

To solve the quadratic equation (0 = x^2 + 3x + 2), you can use the graph by following these steps:

Graph the quadratic function (f(x) = x^2 + 3x + 2).
Find the x-intercepts of the graph, which are the solutions to the equation.
The x-intercepts are the points where the graph intersects the x-axis.
Identify the values of (x) where (f(x) = 0), which are the x-intercepts.
These values represent the solutions to the equation (0 = x^2 + 3x + 2).

When evaluating a one-sided limit, you need to be careful when a quantity is approaching zero since its sign is different depending on which way it is approaching zero from. Let us look at some examples.
