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

Working with polynomial: (8x – 5) + (7x + 4) **Weegy:**
(8x – 5) + (7x + 4)
= 8x + 7x - 5 + 4
= 15x - 1

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

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

= 3x^2 + 7x + 4

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

= 3x^2 + 7x + 4
