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

Irina-Kira [14]

Answer: 13

Step-by-step explanation:

If you remember the quadratic equation formula;

$x=\frac{-b\frac{+}{}\sqrt{b^2-4ac} }{2a}$

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

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

a = 3

b = 7

c = 3

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

Volgvan

6.4(104)+5.2(104)

=(6.4)(10000)+5.2(104)

=64000+5.2(104)

=64000+(5.2)(10000)

=64000+52000

=116000
