Factor the expression. 3r2 – 75 (3r –5)(r + 5) (3r +5)(r – 5) 3(r – 5)(r + 5) 3(r – 5)(r – 5)

factor 3r^2-75

 you would move the 3 to the outside of the parenthesis

then you have 5*5 = 25 and multiply that by the 3 to get the 75

 3(r-5)(r+5)

answer: domain and range mean all possible values of x and y that could be substituted to the inequality. a solution means all possible values that make the inequality statement true. so while the range is still all real numbers, the solution is the shaded area, for which y will always be greater than the line of the function.
