Question

State the value of the discriminant for the equation,
3x^2 + 7x + 3 = 0

Answer 1

Answer: 13

Explanation:

If you remember the quadratic equation formula;

`x=\frac{-b\frac{+}{}√(b^2-4ac) }{2a}`

You can easily extract what is under the root to find the discriminant.

`b^2-4ac=?\\`

a = 3

b = 7

c = 3

`(7)^2-4(3)(3)\\49-36=13`
