Solve 12xdivx2x+4*5

$$12x \div x2x+4 \times 5$$

Evaluate

$$\frac{12x^{2}}{x_{2}}+20$$

Short Solution Steps

Express \frac{12x}{x_{2}}x as a single fraction.

$$\frac{12xx}{x_{2}}+4\times 5$$

Multiply 4 and 5 to get 20.

$$\frac{12xx}{x_{2}}+20$$

To add or subtract expressions, expand them to make their denominators the same. Multiply 20 times \frac{x_{2}}{x_{2}}.

$$\frac{12xx}{x_{2}}+\frac{20x_{2}}{x_{2}}$$

Since \frac{12xx}{x_{2}} and \frac{20x_{2}}{x_{2}} have the same denominator, add them by adding their numerators.

$$\frac{12xx+20x_{2}}{x_{2}}$$

Do the multiplications in 12xx+20x_{2}.

$$\frac{12x^{2}+20x_{2}}{x_{2}}$$

Factor

$$\frac{4\left(3x^{2}+5x_{2}\right)}{x_{2}}$$
