question:Consider the following two examples of geometric objects and the process of determining the points at which they intersect. 1) A parabola defined by the equation y = x^2 + 3x + 2 and a circle defined by the equation x^2 + y^2 = 4. 2) A circle defined by the equation x^2 + y^2 = 9 and an ellipse defined by the equation (x^2 / 4) + (y^2 / 9) = 1. For each pair of objects, describe a general method for finding their points of intersection. Use an algebraic approach and apply it to the specific examples given. In general, when finding the intersection points between two geometric objects defined by algebraic equations, we can use a technique called substitution or elimination to solve for the variables involved. Let's examine each example using this approach. For the first example, the parabola and the circle, we have two equations: y = x^2 + 3x + 2 and x^2 + y^2 = 4. We can substitute the expression for y from the parabola equation into the equation of the circle, yielding: x^2 + (x^2 + 3x + 2)^2 = 4. This equation can be expanded and simplified to obtain a quartic equation in terms of x, which can then be solved to find the x-coordinates of the intersection points. Upon solving the resulting quartic equation, we find the x-coordinates, and then substitute these x-coordinates into either the original parabola equation or the circle equation to obtain the corresponding y-coordinates. Applying this method to the given equations yields x-coordinates that may be real or complex. Once we have the x-coordinates, we can find the corresponding y-coordinates. For the second example, the circle and the ellipse, we have the equations x^2 + y^2 = 9 and (x^2 / 4) + (y^2 / 9) = 1. We can multiply the equation of the ellipse by 36 to eliminate the fractions, resulting in: 9x^2 + 4y^2 = 36. Now we have a system of equations with the circle equation x^2 + y^2 = 9 and the modified ellipse equation 9x^2 + 4y^2 = 36. To eliminate y^2, we can multiply the circle equation by 4, yielding: 4x^2 + 4y^2 = 36. Now we can subtract this equation from the modified ellipse equation to eliminate y^2 and obtain: 5x^2 = 0. The only solution for x is x = 0. Substituting x = 0 back into either the circle equation or the ellipse equation, we can solve for y. These examples illustrate the general method for finding the intersection points between two geometric objects using algebraic techniques. The specific solutions may involve complex numbers, depending on the nature of the intersection points. In conclusion, the method of substitution or elimination can be used to find the intersection points between two geometric objects defined by algebraic equations. The resulting solutions may be real or complex, and the method can be applied to various types of geometric objects, including conic sections and other curves. When using this method, it's essential to carefully manipulate the equations, simplify the expressions, and consider all possible solutions, including complex numbers, to ensure that all intersection points are found.
