This is GCF so ..
-3x^4+12x^3-21x^2

The greatest common factor in that expression is 3x², giving you the expression:

3x²(-x² + 4x -7)

Step-by-step explanation:

All three terms are divisible by three:

3(-x⁴ + 4x³ - 7x²)

Each term is also divisible by x²:

3x²(-x² + 4x -7)

So the greatest common factor is 3x²

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.
