Question

What are the values of a, b, and c in the quadratic equation –2x2 + 4x – 3 = 0?

a = 2, b = 4, c = 3
a = 2, b = 4, c = –3
a = –2, b = 4, c = 3
a = –2, b = 4, c = – 3

Answer 1

By definition, the correct answer is the last option: a = –2, b = 4, c = – 3

Definition of cuadratic function

A quadratic function is a polynomial function with one or more variables in which the highest degree term is of the second degree.

That is, a quadratic function is a type of function that is characterized by being a second degree polynomial, that is, it has a maximum degree of two, which is why it is also called a second degree function.

The general form of a quadratic function is:

f(x)= ax² +bx +c

where a, b, and c are real numbers and a is nonzero.

The graph of a quadratic function is a curve called a parabola. Parabolas open up or down.

Quadratic equation –2x² + 4x – 3 = 0

Comparing with the general form of a quadratic function, you can observe that:

• a=-2
• b=4
• c=-3

Finally, the correct answer is the last option: a = –2, b = 4, c = – 3
