Answer:
discriminant of the quadratic equation is -16, The resulting number is less than zero so there are no real number solutions. Hope its Helps:):)
Step-by-step explanation:
Given : he quadratic equation −1 = 5x² −2x.
To find : What is the value of the discriminant .
Solution : We have given that −1 = 5x² −2x.
−1 = 5x² −2x.
On adding by 1 both sides
0 = 5x² −2x +1
On switching sides
5x² −2x +1 = 0
Compare it standard form of quadratic equation ax² +bx +c = 0.
Here, a = 5, b= -2, c = 1
By Discriminant formula:
D =
Substituting the values
D = .
D = 4 - 20
D = -16.
Therefore, discriminant of the quadratic equation is -16, The resulting number is less than zero so there are no real number solutions.

In -2x
, the exponent will be dealt with first. With (-2x)
, the multiplication is going to be done first. This is determined because of Order of operations.
The answer to this question is :42
Your welcome:)
Answer:
Its 4
Step-by-step explanation:
-4/3 ÷2/-6
first step is to keep -4/3 switch the division sign into a multiplication sign and reverse the second fraction from numerator/denominator to denominator/numerator.
so -4/3*-6/2=24/6=4
