What are the points of intersection of #y=-2x^2-5x+3# and #y=-2x+3#?
2 Answers
Explanation:
To find the pts. of intersection of these two curves, we have to solve
their eqns.
These roots satisfy the given eqns.
Hence, the desired pts. of int. are
At points
Explanation:
Given -
#y=-2x^2-5x+3#
#y=-2x+3#
To find the intersection point of these two curves, set -
#-2x^2-5x+3=-2x+3#
Solve it for
You will get at what values of
#-2x^2-5x+3+2x-3=0#
#-2x^2-3x=0#
#x(-2x-3)=0#
#x=0#
#x=3/(-2)=-1.5#
When
To find the point of intersection, we must know the Y-cordinate
Substitute
#y=-2(0)+3#
#y=3#
At
#y=-2(1.5)+3=3+3=6#
At
