y=5x+6
Algebra Equations Rock!!
Algebra Problem: 2y=x+2z-4; x=4z-4; z=y+2 y=1/2x+z-2 y=1/2(4z-4)+z-2 y=2z-2+z-2 y=3z-4 y=3(y+2)-4 y=3y+6-4 -2y=2 y=-1 z=-1+2 z=1 x=4(1)-4 x=4-4 x=0 y=-1; z=1; x=0 Check: 2y=0+2(1)-4 2y=2-4 2y=-2 y=-1 z=(-1)+2 z=1 x=4(1)-4 x=4-4 x=0
y=(x+3)(x-5) useFOIL (first, outside, inside, last) to get: y=x^2-5x+3x-15 y=x^2-2x-15
y=(x-1)(x+1) use box method x-1 x x^2-x +1 x-1 to get: y=x^2+x-x-1 y=x^2-1
y=(x-2)(x+2)
