Card 1 of 24
How do you check whether (x,y)(x,y)(x,y) solves simultaneous equations?
A
A simultaneous solution is an ordered pair (x,y)(x,y)(x,y) that satisfies every equation in the system.
B
Substituting a linear equation into a quadratic equation usually produces a quadratic in one variable, which may have two valid roots.
C
It gives a repeated root, so there is one intersection.
D
Substitute it into both original equations.
