(Sections 7.1-7.3: Systems of Equations)7.03Apply the ZFP (Zero Factor Property):x=0orx2−3=0x2=3x= ±3Warning: We’re not done yet! We need to find the correspondingy-values.Step 4) Back-substitute intostar.Observe that:3()3=3()3()3()=3 3xy=2−x302−0( )3=232−3()3=2−3 3−32− −3()3=2− −3 3()=2+3 3Step 5) Write the solution set.This is usually required if you are solving a system of equations.Warning: Make sure that your solutions are written in the formx,y(),noty,x().The solution set here is:0,2(),3, 2−3 3(),−3, 2+3 3(){}This consists of three real solutions written as ordered pairs.We assume that ordered pairs are appropriate, since no mention ismade ofzor other variables.
