(4x^2 + 5x + 3) + (3x^2 – 8x - 5)

= 4x^2 + 5x + 3 + 3x^2 – 8x - 5

= (4x^2 + 3x^2) + (5x - 8x) + (3 - 5)

= 7x^2 - 3x - 2

= 4x^2 + 5x + 3 + 3x^2 – 8x - 5

= (4x^2 + 3x^2) + (5x - 8x) + (3 - 5)

= 7x^2 - 3x - 2

(2x^2 + 4)(2x^2- 4) = (2x^2)^2 - 4^2 = 4x^4 - 16

x^2 + x – 72 = 0

(x - 8)(x + 9) = 0;

x - 8 = 0 or x + 9 = 0;

x = 8 or x = -9

Solution set: {-9, 8}

Real Solution: x = -9

(-9)^2 + (-9) – 72 = 0;

81 - 9 - 72 = 0;

72 - 72 = 0;

0 = 0

(x - 8)(x + 9) = 0;

x - 8 = 0 or x + 9 = 0;

x = 8 or x = -9

Solution set: {-9, 8}

Real Solution: x = -9

(-9)^2 + (-9) – 72 = 0;

81 - 9 - 72 = 0;

72 - 72 = 0;

0 = 0

Factor completely: 15x^3y^2 + 25x^2y^2 + 5xy^2 User: Factor completely: x^2 + 9x+ 14
**Weegy:** x^2 + 9x + 14 = (x+7)(x+2) **User:** The sum of three consecutive numbers is 150. Find the numbers. (More)

15x^3y^2 + 25x^2y^2 + 5xy^2 = 5x(3x^2 + 5x + 1)y^2

The sum of three consecutive numbers is 150. The numbers are 49, 50 and 51.

x + (x + 1) + (x + 2) = 150;

3x + 3 = 150;

3x = 150 - 3;

3x = 147;

x = 147/3;

x = 49

49 + 50 + 51 = 150

x + (x + 1) + (x + 2) = 150;

3x + 3 = 150;

3x = 150 - 3;

3x = 147;

x = 147/3;

x = 49

49 + 50 + 51 = 150
