Question

. Identify a, b, and c for use in the Quadratic Formula.
5x^2 =4x - 7

A. a = 5, b = 4, c = -7
B. a = 5, b = -4, c = 7
C. a = -5, b = -4, c = -7
D. a = 4, b = -7, c = 5

Answer 1

bring all terms on one side to get the form \(ax^2+bx+c=0\)
so,
\(5x^2-4x+7=0\)
compare it with \(ax^2+bx+c=0\)

Answer 2

now can you find a,b,c ?
