Answer:
When ever you can’t solve it it considered false like 4 - 12
Step-by-step explanation:
Discriminant of a Quadratic
The number D = b2 – 4ac determined from the coefficients of the equation ax2 + bx + c = 0. The discriminant reveals what type of roots the equation has.
Note: b2 – 4ac comes from the quadratic formula.

<span>Answer:
The cylinder has equation y^2 + z^2 = 1 (with x in [0, 2]).
So, we can write the volume â«â«â« 1 dV as
â«(x = 0 to 2) â«(z = -1 to 1) â«(y = -âš(1 - z^2) to âš(1 - z^2)) 1 dy dz dx.</span>
