4x + 0.8 = 0 or 7 + 2x = 0
For the first equation:4x = -0.8x = -0.8/4x = -0.2
For the second equation:2x = -7x = -7/2x = -3.5
Therefore, the solutions to the equation (4x+0.8)(7+2x) = 0 are x = -0.2 and x = -3.5.
4x + 0.8 = 0 or 7 + 2x = 0
For the first equation:
4x = -0.8
x = -0.8/4
x = -0.2
For the second equation:
2x = -7
x = -7/2
x = -3.5
Therefore, the solutions to the equation (4x+0.8)(7+2x) = 0 are x = -0.2 and x = -3.5.
