Question

) 5х2 + 8х – 3 = 8х +2 ​

Answer 1

Ответ:

x = 1 x= - 1

Пошаговое объяснение:

5х2 + 8х – 3 = 8х +2 ​

5х^2 + 8х – 3 - 8х -2 ​= 0

5х^2 - 5 =0

5*(x^2-1)=0

x^2-1=0

x^2=1

x = 1 x= - 1

Answer 2

To solve the equation 5x^2 + 8x - 3 = 8x + 2, you can start by simplifying the equation and then solving for x. Here are the steps:

1. Subtract 8x from both sides of the equation to eliminate the 8x terms on the right side:

5x^2 + 8x - 3 - 8x = 8x + 2 - 8x

This simplifies to:

5x^2 - 3 = 2

2. Now, add 3 to both sides of the equation to isolate the 5x^2 term:

5x^2 - 3 + 3 = 2 + 3

This simplifies to:

5x^2 = 5

3. Divide both sides of the equation by 5 to solve for x:

(5x^2)/5 = 5/5

This simplifies to:

x^2 = 1

4. To find the value of x, take the square root of both sides of the equation. Remember to consider both the positive and negative square roots:

x = ±√1

x can be either:

x = 1 or x = -1

So, the solutions to the equation 5x^2 + 8x - 3 = 8x + 2 are x = 1 and x = -1.
