If the equation y = 2x squared minus 3x minus 5 is shown on a grid, between which two integers will the graph cross the x-axis (List both crossing areas)
If the equation y = 2x squared minus 3x minus 5 is shown on a grid, between
which two integers will the graph cross the x-axis (List both crossing areas)
y = 2x2 – 3x – 5 The curve crosses the x-axis when y = 0
2x2 – 3x – 5 = 0
(2x – 5)(x + 1) = 0 ==>> (2x – 5) = 0
2x = 5
x = 2.5
(x + 1) = 0
x = – 1
The curve crosses the x-axis at (2.5, 0) and (–1, 0)
