Chapter 7: Q43. (page 462)

Solve the given equation.
$2 x (x + 3) = 2 (x^{2} + 3)$

Short Answer

Expert verified

$x = 1$ is the solution of the given equation.

Step by step solution

Step 1. Define an equation.

In mathematics, an equation is a statement that asserts the equality of two expressions, which are connected by the equal sign $" = "$ .

Step 2. Define the power of a product rule.

Power of a product rule states that if the two exponents of the same base are multiplied then the exponents are added and base remains the same.

$a^{m} . a^{n} = a^{m + n}$

Where, is any non-zero real number.

Step 3. Solve the equation, 2x(2x+3)=2(x2+3).

Use the power of a product rule to solve the equation.

$\begin{matrix} 2 x (x + 3) = 2 (x^{2} + 3) \\ 2 x (x) + 2 x (3) = 2 (x^{2}) + 2 (3) \\ 2 x^{2} + 6 x = 2 x^{2} + 6 \\ 2 x^{2} + 6 x - 2 x^{2} = 6 \\ 6 x = 6 \\ x = \frac{6}{6} \\ x = 1 \end{matrix}$

Therefore, $x = 1$ is the solution of the given equation.
