Answer 3

To simplify the given expression, let's start by expanding the expression inside the parentheses first:

$x^2$ raised to the power of 2: $x^2 \cdot x^2 = x^{2+2} = x^4$

Next, $x^2$ multiplied by -3x: $-3x \cdot x^2 = -3x^{1+2} = -3x^3$

Finally, $x^2$ multiplied by 5: $5 \cdot x^2 = 5x^2$

Now, let's put it all together and simplify the entire expression:

$-2x(x^2 - 3x + 5) = -2x \cdot (x^4 - 3x^3 + 5x^2)$

To complete the simplification, distribute -2x across the terms inside the parentheses:

$-2x \cdot (x^4 - 3x^3 + 5x^2) = -2x \cdot x^4 + 2x \cdot 3x^3 - 2x \cdot 5x^2$

Now, simplify each term:

$= -2x^5 + 6x^4 - 10x^3$

So, the simplified expression is $-2x^5 + 6x^4 - 10x^3$.
