Step-by-step explanation:
¡Aquí puedes aprender todo sobre las multiplicaciones! HAGA CLIC PARA TWITTEAREntonces, la multiplicación 2 x 72 es una suma abreviada.
You can do substitution 2x-2=x^2 -x -6; isolate all terms on one side 0= x^2 -x-2x -6+2; combine like terms x^2 -3x -4=0; factor the quadratic (x-4)(x+1)=0; each term is zero x-4=0 so x=4 and x+1=0 so x=-1. Now, y=2•4-2=6 and y=2•(-1) -2= -4 ; solutions for the system are ( 4,6) and ( -1, -4)
4y^2+4x+1-4y^2+2
4y+1+2
4y+3
