Question

2 х(8X-3)-5х (3х-2)

Answer 1

Ответ:

8х²-3х-15х²+10х=-7х²+7х

Answer 2

Объяснение:

2х(8х-3)-5х(3х-2)

16х²-6х-15х²-10х=0

х²-16х=0

х(х-16)=0

Х=0 или х-16=0 => х=16

Ответ: 0;16.

Answer 3

To simplify the expression 2x(8x - 3) - 5x(3x - 2), you can use the distributive property to expand and combine like terms. Here's the step-by-step process:

1. Distribute the 2x and the -5x to the terms inside the parentheses:

2x(8x - 3) = 16x^2 - 6x -5x(3x - 2) = -15x^2 + 10x

2. Now, you can subtract the second expression from the first:

(16x^2 - 6x) - (-15x^2 + 10x)

3. Remove the parentheses and simplify the expression by combining like terms:

16x^2 - 6x + 15x^2 - 10x

4. Combine the x^2 terms and the x terms:

(16x^2 + 15x^2) - (6x - 10x)

5. Add the x^2 terms and subtract the x terms:

31x^2 - (-4x)

6. Finally, simplify further:

31x^2 + 4x

So, the simplified expression is 31x^2 + 4x.
