Question

What is the discriminant of 3x2 - 10x = -2?

Answer 1

Yes the answer is A. or 76

Answer 2

76

Explanation:

Discriminant is given by the formula
`b^2 -4ac`

Where a is the coefficient of x^2 and b is the coefficient of x and c is the constant term when the quadratic is arranged in the form of
`ax^2+bx+c`

Let's rearrange the given equation:

`3x^2-10x=-2\\3x^2-10x+2=0`

So a = 3

b = -10

c = 2

Plugging into formula we have the discriminant as:

`b^2-4ac\\(-10)^2-4(3)(2)\\100-24\\76`

THe discriminant is 76
