Question

Using the quadratic formula which of the following are the zeros of the quadratic equation below

Answer 1

A.x=(5±)/4

Explanation:

Answer 2

The answer is the option A.

x=(5±
`\sqrt33`)/4

Explanation:

The quadratic formula has the following form for a quadratic equation ax²+bx+c:

x=(-b±
`\sqrt{b^(2) -4ac}`))/(2a)

We apply the quadratic formula and we obtain:

x=(-(-5)±
`\sqrt{5^(2) -4(2)(-1)}`))/(2(2))

x=(-(-5)±
`√(25 +8)`))/(4)

x=(-(-5)±
`√(33)`))/(4)
