Answer:

(x+3)(x-3)

Step-by-step explanation:

rewrite "9" as 3^2

so it is x^2-3^2

You use the difference of squares: a^2-b^2=(a+b)(a-b)

apply it: (x+3)(x-3)

The coordinate of point F will be (1.6,4.2) for the given line segment.

<h3> What is a line segment?</h3>

A line section that can connect two places is referred to as a segment.

In other words, a line segment is just part of a big line that is straight and going unlimited in both directions.

The line is here! It extends endlessly in both directions and has no beginning or conclusion.

Given the F intercept 2 and 3

x = [2(4) + 3(0)]/(2+3)

x = 8/5 = 1.6

Similarly

y = [2(0) + 3 (7)]/(2+3)

y = 21/5 = 4.2

Hence "The coordinate of point F will be (1.6,4.2) for the given line segment".
