The zero-product principle states that if AB = 0, then

s2008m [1.1K]

A = 0 (or) B = 0

Solution:

The zero product principle is most probably used to solve a quadratic equation by factoring the factors.

Let us know the definition of zero product principle.

Zero product principle:

The zero product principle states that if the product of two factors is zero then at least one of the factors must be zero.

This means that if AB = 0, then A = 0 (or) B = 0.

Hence, The zero-product principle states that

if AB = 0, then A = 0 (or) B = 0.

Answer:

6x²+4x

Step-by-step explanation:

The given expressions are 3x²- 4x-4 and 3x²+8x+4.

We need to add these two expressions.

3x²- 4x-4 + 3x²+8x+4 = 3x² + 3x² -4x+8x-4+4

= 6x²+4x

On adding the given expressions, we get the value as 6x²+4x. Hence, the sum of the given expressions is equal to 6x²+4x

$Potential \: \: Energy =(mass) \times (gravity \: acceleration) \times (height) \\$

_________________________________

If gravity acceleration is 10 :

$PE = 25 \times 10 \times 10$

$PE = 2500$

_________________________________

If gravity acceleration is 9.8 :

$PE = 25 \times 9.8 \times 10$

$PE = 25 \times 98$

$PE = 2450$
