Determine the values of a, b, and c for the quadratic equation: 2x2 - 6x - 4 = 0

Step-by-step explanation: The values for a, b, and c come from the

coefficients on our 3 terms in the trinomial.

The value for a comes from the coefficient

on the x² term which in this case is 2.

So we say that a = 2.

The value for b comes from the coefficient

on the x term which in this case is -6.

So we say that b = -6.

The value of c comes from the

constant term which in this case is -4.

So we say that c = -4.

step-by-step explanation:

y = | -2(-2) |     →     y = | 4 |     →     y = 4       ⇒   (-2, 4)

y = | -2(-1) |     →     y = | 2 |     →       y =   2       ⇒   (-1, 2)    

y = | -2(0) |     →     y = | 0 |     →       y = 0         ⇒   (0, 0)

y = | -2(1) |   c →     y = | -2 |     →     y =   2         ⇒   (1, 2)    

y = | -2(2) |     →     y = | - 4 |     →     y =   4         ⇒   (2, 4)
