Question

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

Answer 1

Answer:

answer is first option

${x}^{2} -3x - 5 = 0$

wherein, a = 1, b = -3, c = -5

Answer 2

Answer:

Option (a) is correct.

For given values a = 1 , b = -3 , c = -5 the quadratic equation is  

Step-by-step explanation:

Given : a = 1 , b = -3 , c = -5

We have to write the quadratic equation having a = 1 , b = -3 , c = -5 and choose the correct option.

The standard form of quadratic equation is  , where a, b, c are constant integers.

Given : a = 1 , b = -3 , c = -5

Then Substitute, we get,

 

Thus, the obtained quadratic equation is same as option (a)

Thus, For given values a = 1 , b = -3 , c = -5 the quadratic equation is
