Question

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

Answer 1

Answer:

76

Step-by-step 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

Answer 2

Answer:

Yes the answer is A.  or  76
