Question

Which equation has an a-value of –2, a b-value of 1, and a c-value of 3?

0 = –2x2 + x + 3
0 = 2x2 + x + 3
0 = –2x2 + 3
0 = 2x2 – x + 3

Answer 1

The correct answer would be: 0 = -2x2 + x + 3.

Answer 2

1.
`0=-2x^(2) +x+3`

Step by step explanation:

We are asked to find which of the given equation has our given coefficient values.

Since we know that in quadratic equations a is quadratic coefficient, b is linear coefficient and c is our constant term.

Let us see our given equations one by one.

1.
`0=-2x^(2) +x+3`

We can see that coefficient of quadratic equation in our given option are:

a (quadratic coefficient)=-2

b (linear coefficient)= 1

c (constant) =3

Therefore, 1st option is correct choice.

2.
`0=2x^(2) +x+3`

We can see that coefficient of quadratic equation in our given option are:

a (quadratic coefficient)=2

b (linear coefficient)= 1

c (constant) =3

Therefore, 2nd option is incorrect.

3.
`0=-2x^(2) +3`

We can see that coefficient of quadratic equation in our given option are:

a (quadratic coefficient)=-2

b (linear coefficient)= 0

c (constant) =3

Therefore, 3rd option in incorrect as well.

4.
`0=2x^(2) -x+3`

We can see that coefficient of quadratic equation in our given option are:

a (quadratic coefficient)=2

b (linear coefficient)= -1

c (constant) =3

Therefore, 4th option is incorrect too.
