Weegy: x^2 - 4x -12 = 0
(x + 2) (x - 6) = 0
x + 2 = 0 or x - 6 = 0
x + 2 - 2 = 0 -2 or x - 6 + 6 = 0 + 6
x = -2 or x = 6 User: Solve. A=1/2W(R+S) for W Weegy: A=(1)/(2)*W(R+S)
Since W is on the right-hand side of the equation, [ switch the sides so it is on the left-hand side of the equation.
(1)/(2)*W(R+S)=A
Multiply the rational expressions to get (W(R+S))/(2).
(W(R+S))/(2)=A
Multiply each term in the equation by 2.
(W(R+S))/(2)*2=A*2
Simplify the left-hand side of the equation by canceling the common factors.
W(R+S)=A*2
Multiply A by 2 to get 2A.
W(R+S)=2A
Divide each term in the equation by (R+S).
(W(R+S))/(R+S)=(2A)/(R+S)
Simplify the left-hand side of the equation by canceling the common factors.
W=(2A)/(R+S) ] (More)
