Answer:

x_1=-2.9\\x_2=0.2

Step-by-step explanation:

The first step is to move the 5x to the left side of the equation and then add the like terms:

4x^2+16x-2=5x\\\\4x^2+16x-2-5x=0\\\\4x^2+11x-2=0

Now we can apply the Quadratic formula. This is:

x=\frac{-b\±\sqrt{b^2-4ac}}{2a}

In this case we can identify that:

a=4\\b=11\\c=-2

Finally, we must substitute these values into the Quadratic formula. Then we get:

x=\frac{-11\±\sqrt{(11)^2-4(4)(-2)}}{2(4)}

x_1=-2.9\\x_2=0.2

Answer:

x = 3 or x = 2 or x = -1 or x = -5

Step-by-step explanation:

Solve for x:

((x - 3) (x - 2) (x + 1) (x + 5))/x = 0

Multiply both sides by x:

(x - 3) (x - 2) (x + 1) (x + 5) = 0

Split into four equations:

x - 3 = 0 or x - 2 = 0 or x + 1 = 0 or x + 5 = 0

Add 3 to both sides:

x = 3 or x - 2 = 0 or x + 1 = 0 or x + 5 = 0

Add 2 to both sides:

x = 3 or x = 2 or x + 1 = 0 or x + 5 = 0

Subtract 1 from both sides:

x = 3 or x = 2 or x = -1 or x + 5 = 0

Subtract 5 from both sides:

Answer:  x = 3 or x = 2 or x = -1 or x = -5
