Answer:
76
Step-by-step explanation:
Applying the formula to calculate the discriminant Δ=b2−4(a)(c)
Δ=b2-4(a)(c) with : a=3, b=−10, c=2
Δ=(−10)2−4⋅(3)⋅(2) = 100−24 = 76
The discriminant of the polynomial is equal to 76.
Answer:
Option A.
Step-by-step explanation:
The given equation is
[tex]3x^2-10x=-2[/tex]
It can be rewritten as
[tex]3x^2-10x+2=0[/tex]
If a quadratic equation is [tex]ax^2+bx+c=0[/tex], then discriminant is [tex]D=b^2-4ac[/tex].
In the given equation a=3, b=-10 and c=2. So, the value of discriminant is
[tex]D=(-10)^2-4(3)(2)[/tex]
[tex]D=100-24[/tex]
[tex]D=76[/tex]
Therefore, the correct option is A.
