Question

(х - 5) (2х + 7) = 0

Answer 1

x-5=0 или 2x+7=0. x1=5, 2x= -7, x2= -7/2= -3,5. Ответ: x1=5, x2= -3,5.

Answer 2

To solve the equation (х - 5) (2х + 7) = 0, you can use the zero product property, which states that if the product of two factors is zero, then at least one of the factors must be zero.

So, we set each factor equal to zero and solve for x:

x - 5 = 0 or 2x + 7 = 0

If x - 5 = 0, then adding 5 to both sides gives x = 5.

If 2x + 7 = 0, then subtracting 7 from both sides gives 2x = -7, and then dividing by 2 gives x = -7/2.

Therefore, the solutions to the equation are x = 5 and x = -7/2.
