Question

(4x-3)(-2x-8)=0 Не могу понять как решать

Answer 1

Скобка на скобку короче)
-8х^2-32x+6x+24=0
-8x^2-26x+24=0
8x^2+26x-24=0
D=676-4*8*(-24)=1444=38^2
x1=(38-26)/16=0.75
x2=(-38-26)/16=-4

Answer 2

Solving the Equation (4x-3)(-2x-8)=0

To solve the equation (4x-3)(-2x-8)=0, we can use the zero product property, which states that if the product of two factors is equal to zero, then at least one of the factors must be zero.

1. Apply the Zero Product Property: - (4x-3)(-2x-8)=0 - This means that either (4x-3)=0 or (-2x-8)=0.

2. Solve for x: - For (4x-3)=0: - 4x-3=0 - 4x=3 - x=3/4

- For (-2x-8)=0: - -2x-8=0 - -2x=8 - x=-4

3. Conclusion: - The solutions to the equation (4x-3)(-2x-8)=0 are x=3/4 and x=-4.
