tatuchka [14]
A tangent line is always perpendicular to the radius that shares the point of tangency.  In other words, where your tangent line touches the circle (at only one point), that line is perpendicular to the radius at that point.

Which will result in a perfect square trinomial (3x-5) (-3x-5)?
makvit [3.9K]

Answer:

-9x² + 25

Step-by-step explanation:

To solve, use FOIL. FOIL:

First

Outside

Inside

Last

Solve "First":

(3x)(-3x) = -9x²

Solve "Outside":

(3x)(-5) = -15x

Solve "Inside":

(-5)(-3x) = +15x

Solve "Last":

(-5)(-5) = +25

Combine like terms:

-9x² - 15x + 15x + 25

-9x² (-15x + 15x) + 25

-9x² + 25

-9x² + 25 is your answer.
