Question

At which points does the graph of y=X(squared)+3x-18 intersect the x axis??

Answer 1

Step-by-step explanation:

Let A be the point at which the graph y=x²+3x-18

intersect the x-axis

As the graph intersects x-axis it's coordinate will be (x,0)

putting the value of y =0

x²+3x-18=0

x²+6x-3x-18=0

x(x+6)-3(x+6)=0

(x+6)(x-3)=0

x=-6, or,x=3

The point A maybe (-6,0) or (3,0)
