Question

(2x-3) (4x+3) -8x²=33​

Answer 1

Ответ:

Объяснение:

8x² + 6x - 12x - 9 -8x² = 33

-6x = 42

x = -7

Answer 2

To solve the given equation ($(2x-3)(4x+3) - 8x^2 = 33$), we need to follow these steps:

Step 1: Distribute the terms in the parentheses: $(2x-3)(4x+3) = 8x^2 + 6x - 12x - 9 = 8x^2 - 6x - 9$

Step 2: Substitute the distributed expression back into the original equation: $8x^2 - 6x - 9 - 8x^2 = 33$

Step 3: Simplify the equation: $-6x - 9 = 33$

Step 4: Add 9 to both sides of the equation: $-6x = 42$

Step 5: Divide both sides by -6: $x = -7$

So, the solution to the equation is $x = -7$.
