Answer:

(5n + 4)(5n - 4)

Step-by-step explanation:

This is the difference of perfect squares. It follows a pattern of

(ax + b)(ax - b) where a is the square root of 25 and b is the square root of 16. The square root of 25 is 5, the square root of 16 is 4, so our factored quadratic is

(5n + 4)(5n - 4)

A line is represented by the equation y = 3x - 6. Which is a coordinate of a

Furkat [3]

Answer:

(2,0)

Step-by-step explanation:

Simply plug in the coordinates. y= 3x - 6, so in this case 0= 3(2) - 6 or 0=0, making the point on the line. If the equation is not true like when using (0,3) and getting 3= -6, then the point is not on the line.
