Answer:
6.33... and 0.333...
Step-by-step explanation:
The quadratic formula is
.
It is important because while some quadratics are factorable and can be solved not all are. The formula will solve all quadratic equations and can also give both real and imaginary solutions. Using the formula will require less work than finding the factors if factorable. We will substitute a=9, b=-54 and c=-19.

We will now solve for the plus and the minus.
The plus,,,
and the minus...

Answer:
The answer should be 14/15.

Answer:
<h2>See below</h2>
Step-by-step explanation:
first thing you didn't give any quadratic equation and also didn't allude which method you indeed however I'll give you two methods
- factoring
- quadratic formula
to get elaborately factoring method
see this question which is answered by me
quadratic formula:
by using this formula we can solve quadratic very early
we just need to substitute the value of a,b and c and simply to get x
Answer:
6^3
Step-by-step explanation:
3 × 3 × 3 × 3 × 3 × 3=729
