Question

How many unique real and complex solutions does `3x^2-7x+12=0` have?

Answer 1

Solve `y = 3x^2 - 7x + 12 = 0`

Explanation:

`D = b^2 - 4ac = 49 - 144 = - 95 < 0`
Since D < 0 the equation doesn't have real roots. It has 2 complex roots. Its parabola graph opens upward (a > 0) and is completely above the x-axis.
