Question

3х(2х-5+2х в квадрате )

Answer 1

3x(2x-5+2x)^2 = 3x • (4x - 5)^2 = 3x • (16x^2 - 40x +25) = 48x^3 - 120x^2 + 75x

Answer 2

To simplify the expression, let's start by expanding the square term and then combine like terms:

First, let's expand the square term (2x)^2: (2x)^2 = (2x) * (2x) = 4x^2

Now, let's rewrite the expression with the expanded square term: 3x(2x - 5 + 4x^2)

Next, distribute the 3x to each term inside the parentheses: 3x * 2x = 6x^2 3x * (-5) = -15x

So the simplified expression is: 6x^2 - 15x + 3x * 4x^2

Finally, let's combine like terms: 6x^2 - 15x + 12x^3

So the fully simplified expression is 12x^3 + 6x^2 - 15x.
