Chapter 8: Q16. (page 492)

Solve each equation. Check your solution.
$2 x (x - 5) = 0$

Short Answer

Expert verified

The solution of $2 x (x - 5) = 0$ is $x = 0, 5$ .

Step by step solution

Step 1. Write zero product property.

For any real numbers x and y, if $x y = 0$ then $x = 0, y = 0$ or both x and y equal to zero.

Step 2. Apply zero product property.

Apply zero product property to the given equation, $2 x (x - 5) = 0$ .

$2 x = 0 or x - 5 = 0 x = 0 x = 5$

Therefore, the roots are 0 and 5.

Step 3. Check the obtained solution.

To check whether the obtained solution is correct or not, substitute 0 for x and 5 for x in the given equation and simplify.

$2 \cdot 0 (0 - 5) \overset{?}{=} 0 0 = 0 ✓$

$2 \cdot 5 (5 - 5) \overset{?}{=} 0 10 (0) \overset{?}{=} 0 0 = 0 ✓$

Therefore, the obtained solution is correct.
