Question

(5x-3)*(3-5x)= Помогите пожалуйста!

Answer 1

=15x-25x-9+15x=5x-9.

Answer 2

15х-9-25х-15х=
-25х=-9
25х=9
х=9/25

Answer 3

Solving the Equation (5x-3)*(3-5x)

To solve the equation (5x-3)*(3-5x), we can expand the expression and then solve for x.

Expanding the expression: (5x-3)*(3-5x) = 15x - 25x^2 - 9 + 15x

Combining like terms: 15x - 25x^2 - 9 + 15x = 0

Rearranging the terms: -25x^2 + 30x - 9 = 0

Using the quadratic formula to solve for x: x = (-b ± √(b^2 - 4ac)) / (2a)

Where a = -25, b = 30, and c = -9.

Calculating the discriminant: b^2 - 4ac = 30^2 - 4*(-25)*(-9) = 900 - 900 = 0

Since the discriminant is 0, the equation has real and equal roots.

Using the quadratic formula: x = (-30 ± √0) / (2*(-25)) x = -30 / -50 x = 3/5

Therefore, the solution to the equation (5x-3)*(3-5x) = 0 is: x = 3/5.
