Question

One x-intercept for a parabola is at the point

(-0.8,0). Use the quadratic formula to find the
other x-intercept for the parabola defined by
this equation:
y = 5x2 + 9x +4
Separate the values with a comma. Round, if
necessary, to the nearest hundredth.

Answer 1

The two points where the parabola 5x²+9x+4=y crosses the x-axis are (-0.8,0) and (-1,0).
