Question

I don't understand this problem, can someone help me to please?
For the quadratic equation 8x2 - 55x = -42 give the values of A,B, and C.

Answer 1

Ok. A quadratic equation is in the form \(ax^{2} + bx + c = 0\).Therefore, what are a, b, and c in this quadratic equation? \(8x^{2} - 55x + 42 = 0\)?

Answer 2

Calcmathlete is right,,

Answer 3

@Calcmathlete So is this correct ? A = 8, B = -5, C = 42

Answer 4

@cornitodisc So is this correct ? A = 8, B = -5, C = 42

Answer 5

Not quite.
A = 8 B = -55 and C = 42

Answer 6

Maybe a typo?

Answer 7

yes indeed,,but B= -55

Answer 8

here' an example for your question
Quadratic Function

A quadratic function of the variable x is a function that can be written in the form

f(x) = ax2 + bx + c Function form
y = ax2 + bx + c Equation form

where a, b, and c are fixed numbers (with a ≠ 0). Examples
1. f(x) = 3x2 - 2x + 1 a = 3, b = -2, c = 1
2. g(x) = -x2 a = -1, b = 0, c = 0
3. h(x) = 3x + 1 Not a quadratic function because a = 0
