The x-intercepts of the function y = x2 + 3x + 2, can be determine by the quadratic equation which solves x2 + 3x + 2 = 0. In this case A = 1, B = 3, and C = 2.
Compute x = (-B ± squareroot (B2 - 4AC)) ÷ 2A
x = (-3 ± squareroot (9 - 4)) ÷ 2
x = -1.5 + squareroot (5) ÷ 2 and -1.5 - squareroot (5) ÷ 2
x ~= -0.382 and -2.618
