Question

*The value of b² - 4ac for equation 3x² - 7x - 2 = 0 is …….* 1️⃣ 49 2️⃣ 0 3️⃣ 25 4️⃣ 73

Answer 1

Answer:

refer to the attachment above

Answer 2

Answer:

73

Step-by-step explanation:

General Quadratic equation is represented by $ax^2+bx+c$.

In the given equation($3x^2-7x-2$),

a=3,

b= -7, and

c= -2.

So value of discriminant i.e, D= b^2 -4ac = (-7)(-7)-(4)(3)(-2) =49+24 = 73
