Video Solution

Solution Steps

00:00 Simply

00:03 Let's break down 10 into factors 5 and 2

00:06 Let's break down the power into multiplications

00:15 Let's mark the common factors

00:36 Let's take out the common factors from the parentheses

00:47 Let's reduce what we can

00:54 And this is the solution to the question

Step-by-Step Solution

Let's simplify the given expression:

$\frac{10x^2-2x}{5x-1}$ Remember that we can reduce complete expressions only when both the numerator and denominator are completely factored into multiplication expressions,

We must first use factorization, identify that in the numerator we can factor out a common term, then reduce the expressions in the resulting fraction:

$\frac{10x^2-2x}{5x-1} \\ \frac{2x(5x-1)}{5x-1} \\ \downarrow\\ \boxed{2x}$ Therefore, the correct answer is answer A.

Answer

$2x$
