(x – 4 )(3x + 2) = 0;

x - 4 = 0; x = 4

3x + 2 = 0; 3x = -2; x = -2/3;

x = 4 or x = -2/3

x - 4 = 0; x = 4

3x + 2 = 0; 3x = -2; x = -2/3;

x = 4 or x = -2/3

simplify: show steps (5x – 5 ) – ( 3x – 3) **Weegy:** (5x – 5 ) – ( 3x – 3), first we have to distribute the negative, so it becomes 5x - 5 - 3x + 3. You can skip this step, but we can pair up terms to get: 5x - 3x - 5 + 3. Subtract the 3x from the 5x to get: 2x - 5 + 3. Then add the 3 to the - 5 to get: 2x - 2. Your final answer is 2x - 2.

To get the sum of (5x^2 + 3x ) + ( 2x + 5), combine like terms.

3x and 2x are the only like terms.

3x + 2x = 5x;

The answer is 5x^2 + 5x + 5

3x and 2x are the only like terms.

3x + 2x = 5x;

The answer is 5x^2 + 5x + 5

(4x – 3.5) – (3x + 1.7), to get the difference,

4x - 3x = x;

-3.5 - 1.7 = -5.2

the answer is x - 5.2

4x - 3x = x;

-3.5 - 1.7 = -5.2

the answer is x - 5.2

x^2 + 20 = -9x

x^2 + 9x + 20 = 0

(x + 5)(x + 4) = 0

x + 5 = 0; x = -5

x + 4 = 0; x = -4

x = {-5, -4}

x^2 + 9x + 20 = 0

(x + 5)(x + 4) = 0

x + 5 = 0; x = -5

x + 4 = 0; x = -4

x = {-5, -4}
