Which of the following is the discriminant of the polynomial below? x^2+6x+8

The standard form of a quadratic equation is ,

ax² + bx + c = 0.

And the formula to find the discriminant is b² - 4ac.

Hence, first step is to compare the given equation with this equation to get the value of a, b and c.

After comparing the equations we will get a = 1, b = 6 and c = 8.

So, discriminant = b²- 4ac

=6²-4 (1)(8)

= 36 - 32

= 4

So, discriminant of the given equation is 4.

Hope this heps you!

the answer to the expression is 83

126.66 m²

step-by-step explanation:

the pertinent area formula is a = πr², where r is the radius.

here, a = π(6.35 m)² = 40.32π, or approximately 126.66 m²
