Which values of x satisfy the equation?
x2−4x−2=−x2+4

Move all terms to the left side and set equal to zero. Then set each factor equal to zero.

x=3,−1

hope this is what your looking for

x=3,−1

Step-by-step explanation: I have done this quiz before and i got the answer right! :)

answer: procent 54 wynosi 33,33%

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
