(1-3x)^2-12=(3x-5)^2уравнениеплиз​

Answer 1

Вот все здесь , понятно или ясно

Answer 2

(1-3x)^2-12=(3x-5)^2

Раскрываем скобки, используя формулу сокращенного умножения

1^2-2*3x+9x^2-12=9x^2-2*3x*5+25

-6х-11=-30х+25

-6х+30х=25+11

24х=36

х=1,5

Answer 3

To solve the given equation $(1-3x)^2 - 12 = (3x-5)^2$, you can follow these steps:

Expand both sides of the equation: $(1-3x)^2 - 12 = (3x-5)^2$

Expand the squares: $(1 - 2 \cdot 3x + (3x)^2) - 12 = (9x^2 - 2 \cdot 3 \cdot 5x + 5^2)$

Simplify both sides: $1 - 6x + 9x^2 - 12 = 9x^2 - 30x + 25$

Combine like terms: $9x^2 - 6x - 11 = 9x^2 - 30x + 25$

Subtract $9x^2$ from both sides: $-6x - 11 = -30x + 25$

Add $30x$ to both sides: $24x - 11 = 25$

Add 11 to both sides: $24x = 36$

Divide by 24: $x = \frac{36}{24}$

Simplify the fraction: $x = \frac{3}{2}$

So, the solution to the equation is $x = \frac{3}{2}$.
