Multiple Choice

Write the given quadratic equation in standard form. Identify a, b, and c. $-4x^2+x=8$

a = - 4, b = 0, c = - 8

a = - 4, b = 1, c = 8

a = - 4, b = 1, c = - 8

a = 2, b = 1, c = 0

Verified step by step guidance

Start by writing the given quadratic equation: -4x^2 + x = 8.

To write the equation in standard form, move all terms to one side of the equation. Subtract 8 from both sides to get: -4x^2 + x - 8 = 0.

The standard form of a quadratic equation is ax^2 + bx + c = 0. Compare this with the equation -4x^2 + x - 8 = 0.

Identify the coefficients: a is the coefficient of x^2, b is the coefficient of x, and c is the constant term.

From the equation -4x^2 + x - 8 = 0, we have a = -4, b = 1, and c = -8.
