(2x-3)(3/2x+5)=0

Sagot :

Réponse:

To solve the equation (2x-3)(3/2x + 5) = 0, first set each factor equal to zero:

2x-3 = 0 or 3/2x + 5 = 0

Now solve for x in each equation:

2x - 3 = 0

2x = 3

x = 3/2

3/2x + 5 = 0

3/2x = -5

x = -10/3

Therefore, the solutions to the equation (2x-3)(3/2x + 5) = 0 are x = 3/2 and x = -10/3.

To solve the equation \((2x - 3)\left(\frac{3}{2}x + 5\right) = 0\), we use the property that if a product of two factors is zero, then at least one of the factors must be zero. This gives us two equations to solve:

1. \(2x - 3 = 0\)
2. \(\frac{3}{2}x + 5 = 0\)

Let's solve each equation separately.

### Solving \(2x - 3 = 0\):
Add 3 to both sides:
\[ 2x = 3 \]

Divide both sides by 2:
\[ x = \frac{3}{2} \]

### Solving \(\frac{3}{2}x + 5 = 0\):
Subtract 5 from both sides:
\[ \frac{3}{2}x = -5 \]

Multiply both sides by \(\frac{2}{3}\) to isolate \(x\):
\[ x = -5 \cdot \frac{2}{3} \]
\[ x = -\frac{10}{3} \]

Thus, the solutions to the equation \((2x - 3)\left(\frac{3}{2}x + 5\right) = 0\) are:
\[ x = \frac{3}{2} \quad \text{or} \quad x = -\frac{10}{3} \]
