Subtract the polynomials (−9x2+8x+2)−(4x2+2x−5) a)-5x^2+10x-3 b)-13x^2+6x+7 c)5x^2+6x+10

For each expression use a property to write an equivalent expression.

Identify the converse of the following conditional: if a point is in the first quadrant, then its coordinates are positive. if the coordinates of a point are not positive, then the point is not in the first quadrant. if the coordinates of a point are positive, then the point is in the first quadrant. if a point is in the first quadrant, then its coordinates are positive. if a point is not in the first quadrant, then the coordinates of the point are not positive.
