Question

(8+1 )(2х-3)-(4х-2)^2=1​

Answer 1

Ответ:

(8x-1)(2x-3)-(4x-2)2=1

16x^2-2x-24x+3-8x+4=1

16x^2-30x=0

x(16x-30)=0

x=0

или 16х-30=0

16х=30

х=1 7/8

Answer 2

Let's simplify the given equation step by step:

(8 + 1)(2x - 3) - (4x - 2)^2 = 1

First, simplify the expressions within parentheses:

9(2x - 3) - (4x - 2)^2 = 1

Next, distribute 9 to the terms inside the parentheses:

18x - 27 - (4x - 2)^2 = 1

Expand the square:

18x - 27 - (16x^2 - 16x + 4) = 1

Simplify further by distributing the negative sign:

18x - 27 - 16x^2 + 16x - 4 = 1

Combine like terms:

-16x^2 + 34x - 31 = 1

Move the constant term to the right side:

-16x^2 + 34x - 32 = 0

Now, the equation is in the form of a quadratic equation (-16x^2 + 34x - 32 = 0). You can solve it using various methods such as factoring, completing the square, or using the quadratic formula. However, this equation does not have simple integer solutions. If you have specific requirements or further instructions, please let me know, and I'll be happy to assist you further.
