what is the x-coordinate at the point of intersection of y1= 2(5x + 3) and y2= x2 − 15? consider only the positive value of x, and round the value to nearest hundredth.

Solution

The equation of two curves are

Equating the two curves that is y values, to find their point of Intersection

→  2 × (5 x+3)=x²-15

→10 x +6=x²-15⇒⇒Used distributive property of multiplication with respect to addition

→x² -10 x -15 -6=0

→x² -10 x-21=0

For a Quadratic equation of the type

Using discriminant method to solve the problem

The x coordinate of point of intersection are, 11.78 and -1.78.
