x^2 + 13x + 15 when x = -3

(-3)^2 + 13(-3) + 15

= 9 - 39 + 15;

= -15

(-3)^2 + 13(-3) + 15

= 9 - 39 + 15;

= -15

(12y³ + 8y² + 20y) / (2y)

= (12y³/2y) + (8y²/2y) + (20y/2y)

= 6y^2 + 4y + 10

= (12y³/2y) + (8y²/2y) + (20y/2y)

= 6y^2 + 4y + 10

(3x^2 + 3x) + (4x + 4)

= 3x^2 + 3x + 4x + 4;

= 3x^2 + 7x + 4

= 3x^2 + 3x + 4x + 4;

= 3x^2 + 7x + 4

(6x^2 - 25x - 10) / (3x + 2)

= (6x^2/3x+2) - (25x/3x+2) - (10/3x+2)

= 2x - 29/3 R. 28/3

= (6x^2/3x+2) - (25x/3x+2) - (10/3x+2)

= 2x - 29/3 R. 28/3
