I need help simplifying this radical expression

Step-by-step explanation:

We can simplify this radical expression by expanding the expression inside the radical:

is the same as:

since the exponents ultimately add up. This can be further simplified into:

, and since the 2 values are being squared, and the square root operation is the inverse of that, it cancels out:

u = -(6/7)w

step-by-step explanation:

place all values with 'u' on one side of the equation.

4u + 8w = - 3u + 2w

4u + 3u = 2w - 8w

further simplify the equation by solving the addition and subtraction.

7u = - 6w

make 'u' the independent variable by placing its co-efficient on the right-hand side.

u = - (6/7)w
