Question:

Solve system of equation y=x^2+3x+1,y=-x-3

Answers

Answer:Point Form: (−2,-1)Equation Form:x=  −2,  y=  −1Step-by-step explanation:

Answer:x = -2y = -1Step-by-step explanation:y = x² + 3x + 1       y = -x -3Set the equations equal to each other:x² + 3x + 1 = -x - 3Move all terms to one side:x² + 3x + x + 1 + 3 = 0x² + 4x  + 4 = 0factor:(x + 2)² = 0take square root of both sidesLx + 2 = 0subtract 2 from both sides: x = -2Plug -2 in for x in either of the equations:(-1)²+3(-1)+1 = yy = -1
