The parabola y = 2x & # 178; + 8x + 3 has several common points with the X axis. The coordinates of the common points are
"Mathematical Q & a group" answers for you, hoping to help you. 2x & # 178; + 8x + 3 = 02 (x + 2) & # 178; = 5x + 2 = ± √ 10 / 2x = - 2 ± √ 10 / 2. So: parabola y = 2x & # 178; + 8x + 3 and X axis have two common points, the coordinates of which are (- 2 + √ 10 / 2,0) and (- 2 - √ 10 / 2,0)
