hey guys
 i'm doing this summer packet for an honors geometry class i am planning on being in freshmen year of HS (next year) and i'm stuck on a problem. it seems soo simply.. yet when i try to figure out it seems complicated. please help me asap cause i need to send in the packet soon (before i leave for vacation) DIRECTION: SOLVE THE SYSTEM USING SUBSTITUTION OR ELIMINATION EQUATION 1: x^2 = y + 6 EQUATION 2: 5x = y (note: "^2" means squared) i already firgure out that by substituting "y" you would get: x^2 = 5x +6 but now where do i go from there? |

You then subtract the 5x+6 so that it reads x^2-5x-6=0. Then you factor that out (it comes out to (x-6)(x+1)=0). Then you make each factor equal to zero and solve for x.
