Question

Which equation has an a-value of 1, a b-value of -3, and a c-value of -5 ?

Answer 1

the equation is 0 = -3x - 5 + x^2

Answer 2

Answer: The correct option is

(A)
`0=-3x-5+x^2.`

Step-by-step explanation: We are given to select the correct quadratic equation that has an a-value of 1, b-value of -3 and c-value of -5.

We know that

a general quadratic equation is of the following form :

`ax^2+bx+c=0,~~a\\eq0,`

where a is the coefficient of x²,

b is the coefficient of x

and

c is the constant term.

For the given equation, we get

the coefficient of x², a = 1,

the coefficient of x, b = -3

and

the constant term, c = -5.

Therefore, the required equation is

`1* x^2+(-3)* x+(-5)=0\\\\\Rightarrow 0=-3x-5+x^2.`

Thus, (A) is the correct option.
