What is a reason that we need to be able to use the quadratic formula rather than solving all quadratic equations by graphing?

Here are some examples of how the Quadratic Formula works:

This quadratic happens to factor:

x2 + 3x – 4 = (x + 4)(x – 1) = 0

.

Then, as expected, the solution is x = –4, x = 1.

1; 35 is the ratio

step-by-step explanation:

v = 1/3 a^2h

step-by-step explanation:

if the height is 57.7cm and the height of the slant edge is 18.2cm, then the volume is 1/3 a^2h.
