(5x^2 + x + 7) + (3x^2 - 4x + 3)

= 5x^2 + 3x^2 + x - 4x + 7 + 3;

= 8x^2 - 3x + 10

= 5x^2 + 3x^2 + x - 4x + 7 + 3;

= 8x^2 - 3x + 10

10x - 2 + 3x = 13x -2

9(a+8) - 5(a-10) = 9a + 72 - 5a + 50 = 4a + 122

Note: Multiplication of the same sign is positive (+).

9(a+8) - 5(a-10) = 9a + 72 - 5a + 50 = 4a + 122

9(a + 8) - 5 (a - 10);

9a + 72 - 5a + 50

= 4a + 122

9a + 72 - 5a + 50

= 4a + 122

(5x + 1)(2x - 2)

= 10x^2 - 10x + 2x - 2;

= 10x^2 - 8x - 2

= 10x^2 - 10x + 2x - 2;

= 10x^2 - 8x - 2
