Answer:
y = x² − 6x − 27
Step-by-step explanation:
To distribute, you can use something called FOIL. It stands for First, Outer, Inner, Last.
First, multiply the First term in each factor.
x · x = x²
Now multiply the Outer terms in each factor.
x · 3 = 3x
Next multiply the Inner terms in each factor.
-9 · x = -9x
Finally, multiply the Last terms in each factor.
-9 · 3 = -27
Add them all up:
x² + 3x − 9x − 27
x² − 6x − 27

Answer:
I would use quaro is is faster.
Step-by-step explanation:
I believe the correct answer is false. Quadratic equations that can be solved using the quadratic formula cannot always be solved by factoring. <span>Not </span>all quadratic equations can<span> be </span>solved by factoring<span>. Another method that can be used is completing the square. Hope this answers the question.</span>
