Question

X(4x+11)-7(x²-5x)=-3x(x+3)решите пожалуйстс

Answer 1

Х( 4х + 11 ) - 7( х^2 - 5х ) = - 3х( Х + 3 )
4х^2 + 11х - 7х^2 + 35х = - 3х^2 - 9х
- 3х^2 + 46х = - 3х^2 - 9х
46х + 9х = 0
55х = 0
Х = 0

Answer 2

4x²+11x-7x²-35x+3x²-9x=o
-33x=o
x=-33

Answer 3

To solve the equation X(4x+11)-7(x²-5x)=-3x(x+3), we can follow these steps:

Step 1: Distribute the terms on both sides of the equation: X * 4x + X * 11 - 7 * x² + 7 * 5x = -3x * x - 3x * 3

Simplifying the equation, we have: 4x² + 11X - 7x² + 35x = -3x² - 9x

Step 2: Combine like terms on both sides of the equation: (4x² - 7x² - (-3x²)) + (11X + 35x - 9x) = 0

Simplifying further, we have: -3x² + 37x = 0

Step 3: Factor out the common term: x(-3x + 37) = 0

Step 4: Set each factor equal to zero and solve for x: x = 0 -3x + 37 = 0

Solving the second equation, we have: -3x = -37 x = -37 / -3 x = 37 / 3

Therefore, the solutions to the equation X(4x+11)-7(x²-5x)=-3x(x+3) are x = 0 and x = 37/3.
