Answer:

$x = 4,-2$

Step-by-step explanation:

Step 1: Set each factor to zero then solve

x - 4 = 0

Add 4 to both sides to get x by itself

$x - 4 + 4 = 0 + 4$

$x = 4$

x + 2 = 0

Subtract 2 to both sides to get x by itself

$x + 2 - 2 = 0 - 2$

$x = -2$

Answer: $x = 4,-2$

Answer:

$5a^2+12b^2-40b$

Step-by-step explanation:

First distribute the -4 to the 2b and -3b. This leaves you with $5a^2-8b+12b(b+4)$

Now you can distribute the 12b to b and +4. This leaves you with $5a^2-8b+12b^2+48b$

Now you can combine your like terms leaving you with $5a^2+12b^2-40b$ .

1/3 ( x - 10) = -4 ???

Pepsi [2]

Answer:

$x = - 2$

Step-by-step explanation:

1) Simplify 1/3 ( x - 10) to x-10/3.

$\frac{x - 10}{3} = - 4$

2) Multiply both sides by 3.

$x - 10 = - 4 \times 3$

Simplify 4 × 3 to 12.

$x - 10 = - 12$

4) Add 10 to both sides.

$x = - 12 + 10$

5) Simplify -12 + 10 to -2.

$x = - 2$

So, therefor, the answer is, x = -2.
