What is the value of the discriminant of the quadratic equation −1 = 5x2 −2x, and what does its value mean about the number of r
joja [24]
The correct answer for this question is "The discriminant is equal to −16, which means the equation has no real number solutions."

<span> −1 = 5x2 −2x
</span><span>5x2 −2x + 1 = 0
</span>
To get the discriminant value, use this formula
= b^2 - 4ac
= (-2)^2 - 4(5)(1)
= 4 - 20
= -16
