Question

2х + 15 (все это в корне) = х

Answer 1

√2х + 15 = х 
2х +15 = х∧2
х∧2 - 2х -15 = 0 
дескр -т = 64
х1 = 2+8 делить на 2 = 5 
х2 = 2-8 делить на 2 = -3
О-т 5 -3 

Answer 2

To solve the equation 2√(x) + 15 = x, we can follow these steps:

1. Start by isolating the square root term on one side of the equation: 2√(x) = x - 15

2. Square both sides of the equation to eliminate the square root: (2√(x))^2 = (x - 15)^2 4x = x^2 - 30x + 225

3. Rearrange the equation to form a quadratic equation: x^2 - 34x + 225 = 0

4. Solve the quadratic equation using factoring, completing the square, or the quadratic formula. In this case, let's use factoring: (x - 9)(x - 25) = 0

   Setting each factor equal to zero: x - 9 = 0 or x - 25 = 0

   Solving for x: x = 9 or x = 25

So the equation 2√(x) + 15 = x has two solutions: x = 9 and x = 25.
