Determine the value of a, b, and c for the quadratic equation: 4x2- 8x = 3

Rufina [12.5K]

Answer:

B. a = 4, b = -8, c = -3

Step-by-step explanation:

The quadratic equation given is:

$4x^2- 8x = 3$

The general form of a quadratic equation is given as:

$ax^2 + bx +c = 0$

Let us put the given equation in this form and then compare with the general form of the quadratic equation.

$4x^2- 8x = 3\\\\4x^2 - 8x - 3 = 0$

Therefore, by comparing:

a = 4

b = -8

c = -3

The correct option is B

ahrayia [7]

Answer:

k < - 1

Step-by-step explanation:

28 + 3k < 5(-3-8k)

28 + 3k < - 15 - 40k

28 + 15 < - 40k - 3k

43 < - 43k

43/- 43 > k (switch signs because 43 is negative)

k < -1
